How to convert ounces to kilograms

One ounce weighs 31.1035 grams and one kilogram weighs 1,000 grams, so 1 ounce = 0.0311 kilograms. Multiply any amount in ounces by 0.0311 to get kilograms, or divide by 0.0311 to go back.

Example

10 ounces × 0.0311 = 0.311 kilograms. At today's price, that weight of pure gold is worth $41,405.

Why units matter for precious metals

Bullion is priced in troy ounces, jewelry in grams, South Asian markets in tolas and Chinese markets in taels. Mixing up the avoirdupois ounce (28.35 g) and troy ounce (31.10 g) is a common 9.7% error when comparing prices.

  • Ask sellers which ounce they mean.
  • Convert everything to grams before comparing offers.
  • Use the exact factors on this page rather than rounded ones for large amounts.

Live values use MetalflowAPI prices.
