Tolas to Kilograms: The Complete Guide for Bulk Bullion Trading

The Wholesale Perspective: Why Kilograms Matter in Bulk Gold

For the average retail consumer, the tola and the gram are the only two units that matter. However, for the wholesale jewelry manufacturer sitting in a workshop in Mumbai, or the import/export bullion trader clearing customs at Dubai International Airport, the gram is too small a unit to be practical.

Massive international gold shipments are dominated by the 1-Kilogram Gold Bar. These bars are the standard unit of settlement for the Shanghai Gold Exchange and a massive component of physical deliverance in Dubai and India. The London Bullion Market Association (LBMA), the global authority on gold bar standards, recognizes the 1 kg bar as the primary trading unit for institutional physical gold.

If you are a jewelry store owner importing Kilo bars to melt down and manufacture into 22-Karat string necklaces, you must know exactly how many "tolas" of inventory you can extract from that 1,000-gram brick of pure 24K gold. Similarly, if you are a central bank reserve manager, a gold refinery operator, or a logistics company transporting bullion across borders, the tola-to-kilogram conversion is a calculation you will perform hundreds of times per year.

Why Bulk Gold Is Measured in Kilograms Internationally

The kilogram became the dominant unit for bulk gold trading for several practical reasons:

• Universal metric standard: The kilogram is recognized in every country on earth, eliminating confusion between regional units like the tola, baht, chi, and don
• Exchange compatibility: The Shanghai Gold Exchange, Dubai Gold and Commodities Exchange (DGCX), and Multi Commodity Exchange of India (MCX) all quote contracts in kilograms
• Customs and taxation: Every country's customs authority uses the metric system for import/export declarations, duties, and taxation of precious metals
• Refinery output: Major gold refineries (PAMP, Valcambi, Metalor, MMTC-PAMP) produce standard bars in metric weights: 1 gram, 10 grams, 100 grams, 1 kilogram, and 12.5 kilograms

Despite this international standardization, the tola remains deeply embedded in the retail gold markets of India, Pakistan, Bangladesh, Nepal, and the UAE. This creates a constant need for conversion between the two systems.

The Detailed Tola to Kilogram Conversion Formula

The conversion is a straightforward application of metric division. By definition in the metric system, 1 Kilogram equals exactly 1,000 grams.

We know from the 1833 British standardization that 1 historical Tola equals 11.6638038 grams. You can verify this using our gram to tola converter.

Therefore, a single 1-Kilogram bar of gold contains approximately 85.735 tolas.

The Reverse: Tola to Kilogram Conversion

Conversely, if a wealthy family wishes to liquidate a massive estate holding 200 tolas of inherited gold bullion, and the bullion dealer quotes the buyback rate exclusively in "price per Kilo," how many Kilograms is the family actually holding?

Quick Conversion Examples

Here are some common conversions that bulk traders encounter daily:

• 10 tola = 10 × 11.6638038g = 116.638g = 0.116638 kg
• 50 tola = 50 × 11.6638038g = 583.19g = 0.58319 kg
• 100 tola = 100 × 11.6638038g = 1,166.38g = 1.16638 kg
• 500 tola = 500 × 11.6638038g = 5,831.90g = 5.83190 kg
• 1,000 tola = 1,000 × 11.6638038g = 11,663.80g = 11.66380 kg

Comprehensive Tolas to Kilograms Conversion Table

The following table provides instant reference for converting common tola quantities to kilograms. This table is essential for wholesale bullion dealers, jewelers placing bulk orders, and investors managing large gold portfolios.

Use our tola to gram converter for precise calculations on any custom quantity.

The TT Bar: 10 Tola = 116.638 Grams = 0.116638 kg

The 10-Tola bar, universally known as the "TT bar," is one of the most iconic and widely traded gold bar formats in the world. Manufactured primarily by Swiss refineries like PAMP Suisse, Valcambi, and Argor-Heraeus, the TT bar is specifically designed for the South Asian and Middle Eastern markets where gold is traditionally measured in tolas.

TT Bar Specifications

• Weight: 10 tola = 116.6380 grams = 0.116638 kg
• Purity: 999.9 fine (24K, 99.99% pure gold)
• Dimensions: Approximately 47mm x 27mm x 5.5mm (varies slightly by refinery)
• LBMA accredited: TT bars from recognized refineries carry the LBMA Good Delivery stamp

TT Bars to Kilo Bars: The Conversion

For high-net-worth investors in the Middle East and South Asia, there is an ongoing debate regarding physical storage efficiency: Should you buy 1-Kilogram Bars or 10-Tola (TT Bars)?

A single TT bar weighs 116.638 grams. Therefore, it takes roughly 8.57 TT Bars to equal the exact mass of a single 1-Kilogram bar (1,000g ÷ 116.638g = 8.574).

• The Kilo Bar Advantage: Offers the absolute lowest possible premium over the spot price because you are buying wholesale bulk. Excellent for deep vault storage. A single 1 kg bar is easier to inventory than 8.57 separate TT bars.
• The TT Bar Advantage: Offers infinitely better fractional liquidity. As discussed in our investment guide, if you need a quick $8,000, you can sell a single TT bar. You cannot easily shear $8,000 worth of gold off a solid 1-Kilo brick without destroying its assay value.

Standard Gold Bar Sizes in Kilograms and Their Tola Equivalents

The global gold market uses several standardized bar sizes. Understanding each size in both kilograms and tolas is essential for anyone operating across the traditional and metric systems. Here is a complete breakdown of every major bar format:

The 1-Kilogram Bar (85.735 Tola)

The 1 kg gold bar is the workhorse of the Asian and Middle Eastern wholesale markets. Also known as the "kilobar," it is the standard settlement unit on the Shanghai Gold Exchange and is widely traded in Dubai, Mumbai, and Singapore.

• Weight: 1,000 grams = 85.735 tola
• Purity: Minimum 995 fineness (99.5% pure) for exchange delivery, though most are 999.9
• Approximate value: At $85 per gram, a 1 kg bar is worth approximately $85,000
• Primary exchanges: SGE, DGCX, MCX, Istanbul Gold Exchange

This is the bar format most commonly imported by wholesale gold dealers in tola-using countries. A jeweler importing 10 kilo bars receives 857.35 tolas of raw material for manufacturing.

The 400 Troy Ounce Bar (London Good Delivery) — 12.4 kg = 1,063.1 Tola

The 400 troy ounce bar is the gold standard (literally) of the international bullion market. Also called the "London Good Delivery" bar, it is the format used for settlement on the London Bullion Market and stored in central bank vaults worldwide.

• Weight: 350-430 troy ounces (the "400 oz" is nominal); typically around 12.4 kilograms
• Tola equivalent: 12,400g ÷ 11.6638g = approximately 1,063.1 tola
• Purity: Minimum 995 fineness
• Approximate value: At current prices, a single London Good Delivery bar is worth approximately $1,000,000+

These bars are not handled by retail investors or jewelers. They are the exclusive domain of central banks, sovereign wealth funds, and LBMA-accredited vault operators like Brink's, Loomis, and Malca-Amit.

Other Standard Bar Sizes

• 100 gram bar = 0.1 kg = 8.573 tola — Popular retail investment bar
• 250 gram bar = 0.25 kg = 21.434 tola — Mid-range investment bar
• 500 gram bar = 0.5 kg = 42.868 tola — Half-kilo institutional bar
• 5 kg bar = 5.0 kg = 428.675 tola — Used in inter-bank gold transfers
• 12.5 kg bar (400 oz) = 12.5 kg = 1,071.688 tola — London Good Delivery standard

Accounting for the "10-Gram" Tola Myth in Bulk Calculations

As we constantly reiterate across our informational series, you must be hyper-vigilant regarding which "tola" a local dealer is referencing. While the above mathematics use the true 11.66g traditional standard, many modern retail jewelers use the colloquial "10-gram" tola.

If a jeweler uses the 10-gram metric shortcut, the math changes drastically:

• 1 Kilogram (1,000g) ÷ 10g = 100 "Metric" Tolas
• 1 Kilogram (1,000g) ÷ 11.6638g = 85.735 "Traditional" Tolas
• Difference: 100 - 85.735 = 14.265 tola discrepancy per kilogram

If you purchase a 1 Kilo bar, and a local jeweler offers to buy it from you at a rate of "$850 per tola," you must force them to clarify the denominator. Are they going to pay you for 85.73 tolas (the correct historical standard) or 100 tolas (the modern shortcut)? At $850 per tola, that 14.265-tola difference equals a $12,125 pricing error. Establish this immediately to avoid a catastrophic pricing error during liquidation.

Central Bank Gold Reserves in Tola Equivalents

Central banks are among the largest holders of physical gold in the world. For readers in tola-using countries, understanding these reserves in tola terms provides a fascinating sense of scale.

Reserve Bank of India (RBI)

India's central bank holds one of the largest gold reserves in the world, reflecting gold's deep cultural and economic significance on the subcontinent:

• Total gold reserves: Approximately 803 tonnes (as of late 2024)
• In kilograms: 803,000 kg
• In tola: 803,000 × 85.735 = approximately 68,845,005 tola
• In TT bars: 68,845,005 ÷ 10 = approximately 6,884,500 TT bars

India has been actively increasing its gold reserves in recent years, purchasing gold on international markets to diversify away from US dollar-denominated assets. Every tonne added equals 85,735 additional tolas in the national vault.

State Bank of Pakistan (SBP)

Pakistan's gold reserves are considerably smaller but still significant:

• Total gold reserves: Approximately 64.6 tonnes
• In kilograms: 64,600 kg
• In tola: 64,600 × 85.735 = approximately 5,538,481 tola

These reserves are stored in a combination of domestic vaults and international custodial accounts at institutions like the Bank of England and the Federal Reserve Bank of New York.

Wholesale Gold Pricing: Per Kilogram vs Per Tola Comparison

Wholesale gold prices are quoted differently depending on the market. Understanding how to convert between per-kilogram and per-tola pricing is essential for international traders. You can track current rates on our gold price per tola page.

How Wholesale Pricing Works

The international spot price of gold is quoted in US dollars per troy ounce (XAU/USD). However, when gold physically enters tola-based markets, the pricing is converted as follows:

1. International spot: USD per troy ounce (31.1035 grams)
2. Convert to per-gram: Spot price ÷ 31.1035 = USD per gram
3. Convert to per-kg: USD per gram × 1,000 = USD per kilogram
4. Convert to per-tola: USD per gram × 11.6638038 = USD per tola

Price Example with Real Conversion

Suppose the international gold spot price is $2,650 per troy ounce:

• Per gram: $2,650 ÷ 31.1035 = $85.21 per gram
• Per kilogram: $85.21 × 1,000 = $85,210 per kg
• Per tola: $85.21 × 11.6638 = $993.84 per tola
• Per TT bar (10 tola): $993.84 × 10 = $9,938.40 per TT bar

A wholesale jeweler importing a 1 kg bar at $85,210 can then price out individual tola pieces for retail sale. The wholesale-to-retail markup includes the jeweler's margin, making charges, and local taxes.

Logistics of Transporting Bulk Gold: Weight Limits and Tola Calculations

Physically moving large quantities of gold is one of the most challenging aspects of the bullion trade. The extreme density of gold (19.3 grams per cubic centimeter) means that even modest volumes are extraordinarily heavy.

Airline Transport Limits

Gold is frequently transported by air, particularly between refining centers (Switzerland, UAE) and consumption markets (India, Pakistan, Bangladesh). Key logistics considerations include:

• Standard air freight pallet: Airlines typically limit gold shipments to 250 kg per pallet due to floor loading limits
• 250 kg in tola: 250 × 85.735 = 21,433.75 tola (or approximately 2,143 TT bars)
• Insurance requirements: Shipments are insured per kilogram, so precise tola-to-kg conversion is critical for accurate insurance coverage
• Customs declaration: Gold must be declared in metric units (grams or kilograms) at every international border, even if the commercial invoice quotes the quantity in tolas

Secure Ground Transport

Within countries, gold is transported by armored vehicle. A single armored transport vehicle can carry significantly more weight than an air freight pallet:

• Typical load: 500 kg to 2,000 kg per vehicle
• In tola: 500 kg = 42,867.5 tola; 2,000 kg = 171,470 tola
• Security cost: Priced per kilogram transported, making the tola-to-kg conversion essential for cost estimation

Import/Export Regulations: Gold Weight Declarations in Tola and Kilogram

Every country that imports or exports gold has specific regulations governing weight declarations, duty calculations, and reporting thresholds. Understanding these rules is critical for compliance.

India's Gold Import Regulations

India is the world's second-largest gold importer. Key regulations include:

• Import duty: Currently 15% customs duty on gold imports (basic customs duty + agriculture infrastructure development cess)
• Duty calculation: Based on weight in kilograms and the notified tariff value per 10 grams, which the government updates periodically
• Passenger allowance: Indian residents returning from abroad can carry up to 1 kg of gold (approximately 85.735 tola) subject to payment of duty. This limit applies per passenger
• Declaration requirement: All gold above the duty-free threshold must be declared on the customs form in grams or kilograms

UAE Gold Export and Re-Export

Dubai is the world's largest gold re-export hub. Gold arrives from African mines and Swiss refineries, is processed in Dubai's free zones, and is re-exported primarily to India and East Asia:

• No export duty: The UAE does not levy export duties on gold, making it a globally competitive hub
• Documentation: All exports require a certificate of origin, assay certificate, and weight declaration in metric units
• DMCC regulation: The Dubai Multi Commodities Centre requires all gold traded through its platform to be weighed and declared in kilograms

Refinery Standards: Converting Raw Gold Between Tola and Kilogram Measures

Gold refineries play a critical role in the supply chain by converting raw gold (ore concentrate, scrap jewelry, dore bars) into pure, standardized bars. The tola-to-kilogram conversion is central to refinery operations.

The Refining Process

When a jeweler or dealer sends scrap gold to a refinery, the process follows a specific flow:

1. Receiving and weighing: The scrap gold is weighed in kilograms upon receipt. If the sender's documentation lists quantities in tolas, the refinery converts to kg for its internal records (e.g., 100 tola of scrap = 1.16638 kg)
2. Assaying: A sample is taken and tested to determine the purity. If the scrap is old 22K (916) jewelry, only 91.6% of the gross weight is pure gold
3. Fine gold calculation: Gross weight × purity = fine gold content. For example, 1.16638 kg of 22K scrap = 1.16638 × 0.916 = 1.06838 kg of fine gold
4. Output: The refinery produces standardized bars (1 kg, TT bars, etc.) from the refined fine gold
5. Settlement: The sender receives payment or physical bars based on the fine gold content, minus refining charges

Refining Charges and Tola Conversions

Refineries typically charge on a per-kilogram basis. Understanding the conversion helps sellers estimate their costs:

• Typical refining charge: $1.50 to $4.00 per gram of fine gold, depending on volume and purity of input material
• Per tola refining cost: At $2.50/gram, refining 1 tola (11.6638g) costs approximately $29.16
• Per kg refining cost: At $2.50/gram, refining 1 kg costs approximately $2,500
• Break-even consideration: At current gold prices, refining charges represent less than 3% of the metal's value, making it economical to refine even small quantities

Frequently Asked Questions About Tola to Kilogram Conversion

How many tola in 1 kg gold?

There are 85.735 tola in 1 kilogram of gold. This is calculated by dividing 1,000 grams (1 kg) by 11.6638038 grams (the weight of 1 tola). This conversion factor is the standard used across all international bullion markets. Use our gram to tola converter to verify this calculation instantly.

How to convert 100 tola to kg?

To convert 100 tola to kilograms, multiply 100 by the weight of 1 tola in grams (11.6638038g), then divide by 1,000: 100 × 11.6638038 ÷ 1,000 = 1.16638 kg. So 100 tola of gold equals approximately 1.166 kilograms. This is slightly more than one standard 1 kg gold bar.

What is the weight of a standard gold bar in tola?

The standard 1-kilogram gold bar weighs 85.735 tola. The 10-Tola (TT) bar weighs exactly 10 tola (116.638 grams). The large London Good Delivery 400 troy ounce bar weighs approximately 12.4 kg or 1,063 tola. For a complete comparison, refer to our gold weight units guide.

How many tola in 10 grams?

There are 0.8573 tola in 10 grams. This is calculated by dividing 10 grams by 11.6638038 grams per tola: 10 ÷ 11.6638038 = 0.8573. In other words, 10 grams is slightly less than 1 tola. You can verify this using our tola to gram converter. Note that 1 tola = 11.6638038 grams, not 10 grams as is sometimes incorrectly assumed.

What does 85.735 tola equal?

85.735 tola equals exactly 1 kilogram (1,000 grams). This is the fundamental conversion constant between the traditional tola system and the international metric system. When a wholesale bullion dealer says "1 kilo bar," they are referring to a bar that contains 85.735 traditional tolas of gold. This number is derived from 1,000g ÷ 11.6638038g = 85.73528 tola.

How do I calculate the value of gold in both tola and kilograms?

First, check the international spot price per troy ounce. Divide by 31.1035 to get the price per gram. Multiply by 11.6638038 for the price per tola, or multiply by 1,000 for the price per kilogram. For example, at $2,650/oz: price per gram = $85.21, price per tola = $993.84, and price per kilogram = $85,210. Both the per-tola and per-kilogram prices reflect the same underlying gold value, just expressed in different weight units.

Conclusion: Mastering the Tola-to-Kilogram Bridge

Understanding the bridge between the Tola and the Kilogram is the hallmark of stepping out of the retail jewelry market and into the world of institutional bullion trading. The core constant to remember is simple: 1 kilogram = 85.735 tola, and 1 tola = 11.6638038 grams = 0.0116638 kg.

Whether you are importing gold for manufacturing, storing generational wealth in a family vault, transporting bullion across international borders, or reconciling a refinery settlement statement, keeping the 85.735 tola-per-kilo constant in mind will ensure your ledgers remain perfectly balanced.
