Kilograms to ounces
Kilograms and ounces both measure mass, so the conversion is a fixed multiply. One kilogram equals 1,000 grams, and one avoirdupois ounce is 28.349523 grams, so a kilogram is 35.27396 ounces. Multiply your kilograms by 35.27396 to get ounces.
The same kilogram is 2.20462 pounds, since there are 16 ounces in a pound. Half a kilogram is about 17.6 ounces; a five-kilogram bag is roughly 176 ounces.
The right kind of ounce
This tool uses the avoirdupois ounce, the everyday ounce for food and packages. It is different from the troy ounce used for gold and silver, which is heavier at about 31.10 grams — so a kilogram is only about 32.15 troy ounces. Do not use this converter for precious metals.
Weight ounces are also different from fluid ounces, which measure volume. Kilograms convert cleanly to weight ounces without any density.
How it’s calculated
Ounces = kilograms × 1000 ÷ 28.349523125 (that is × 35.27396195). Pounds = kilograms × 2.20462262; grams = kilograms × 1000. Uses the avoirdupois ounce and NIST factors.
Uses the avoirdupois ounce (28.35 g), not the troy ounce (31.10 g) used for precious metals.

Common mistakes
- Using troy ounces (31.10 g) instead of avoirdupois ounces (28.35 g) for everyday weights.
- Confusing weight ounces with fluid ounces, which measure volume, not mass.
- Rounding 35.274 too hard on large weights, where the fraction adds up.
- Mixing kilograms with pounds mid-calculation instead of converting once.
