Convert gold weight between kilograms and troy ounces in either direction.
Enter a weight, select the conversion you need, and calculate the result
using the standard precious-metal conversion of 1 troy ounce =
31.1034768 grams.
Kilograms to Troy Ounces Gold Conversion
Precious metals such as gold are commonly quoted and traded using troy
ounces. One troy ounce equals exactly 31.1034768 grams.
Since one kilogram contains 1,000 grams, one kilogram is approximately
32.1507465686 troy ounces.
Troy Ounces = Kilograms × 32.1507465686
For example, 1 kilogram of gold converts to approximately
32.15074657 troy ounces.
1 × 32.1507465686 ≈ 32.1507465686 troy ounces
Troy Ounces to Kilograms Gold Conversion
To convert troy ounces into kilograms, multiply the troy-ounce weight by
0.0311034768.
Kilograms = Troy Ounces × 0.0311034768
For example, 32.1507465686 troy ounces is approximately one kilogram.
32.1507465686 × 0.0311034768 ≈ 1 kg

What Is a Troy Ounce?
A troy ounce is the standard ounce used for weighing and pricing many
precious metals, including gold, silver, platinum and palladium. It is
different from the avoirdupois ounce commonly used for everyday products.
1 troy ounce = 31.1034768 grams
1 kilogram ≈ 32.1507465686 troy ounces
This distinction is important when reading gold prices. A gold price quoted
per troy ounce should not be treated as a price per ordinary ounce.
Troy Ounce Versus Regular Ounce
The troy ounce and avoirdupois ounce are different units. A troy ounce
weighs 31.1034768 grams, while a standard avoirdupois ounce is approximately
28.349523125 grams.

For gold calculations, use the troy ounce unless the source explicitly
states another measurement.
Does Gold Purity Affect the Conversion?
No. The kilogram-to-troy-ounce conversion is a mass conversion and does
not depend on whether the gold is 24K, 22K, 18K or another fineness.
Purity matters separately when determining the amount of fine gold within
an alloy.
Fine Gold Weight = Gross Weight × Purity Fraction
For example, a 1 kg gold alloy remains 1 kg regardless of its fineness.
The fine-gold content is calculated separately using its fineness.
Kilograms in Gold Trading and Bullion
Kilograms are particularly useful for describing larger quantities of
precious metal, while troy ounces are widely used for market quotations,
bullion specifications and precious-metal trading.
A one-kilogram gold bar therefore represents approximately
32.15074657 troy ounces of gross mass. Converting between the units can
make specifications and price quotations easier to compare.
Weight specifications
Bullion products may be described by their mass in kilograms or troy
ounces. Converting the units helps verify that the stated quantities
are consistent.
Price comparison
A gold price quoted per troy ounce can be related to a kilogram price
after converting the weight units.
Inventory calculations
Larger precious-metal inventories may be recorded in kilograms while
market data is quoted in troy ounces. Unit conversion helps maintain
consistent records.

Using the Conversion for Gold Prices
If a gold price is quoted per troy ounce and you need an equivalent
kilogram price, multiply the troy-ounce price by approximately
32.1507465686.
Price per kg =
Price per troy ounce × 32.1507465686
If a price is quoted per kilogram and you need a troy-ounce equivalent,
divide the kilogram price by approximately 32.1507465686.
Price per troy ounce =
Price per kg ÷ 32.1507465686
Actual gold pricing can also include purity differences, dealer premiums,
fabrication charges, taxes, shipping and other costs, so a simple unit
conversion should not be treated as a complete valuation.
Important Limitations
This calculator converts mass between kilograms and troy ounces. It does
not determine gold purity, authenticity, market value, dealer buyback
value or fabrication charges.
It does not use live gold prices. Weight conversion should therefore be
kept separate from any current-market valuation.
For physical bullion or jewellery, use verified scale measurements and
reliable product specifications for decisions involving actual metal.
