Kilogram to Ounce (kg to oz)
Result
35.27396195 Ounce
Formula
oz = kg × 35.27396195
1 kg = 35.27396195 oz, and 1 oz = 0.02834952313 kg.
The kilogram is the SI base unit of mass, defined through the Planck constant since 2019. The international avoirdupois pound is exactly 0.45359237 kg; the ounce is 1/16 lb and the stone 14 lb.
Worked examples
- 1 kg × 35.27396195 = 35.273962 oz
- 10 kg × 35.27396195 = 352.73962 oz
- 100 kg × 35.27396195 = 3,527.3962 oz
Common mistakes
- Precious metals use the troy ounce (31.1034768 g), about 10% heavier than the avoirdupois ounce (28.349523125 g) used for food and parcels.
- "Ton" is ambiguous: the metric tonne used here is 1,000 kg, the US short ton 907.18474 kg and the UK long ton 1,016.0469088 kg.
- Kilograms and pounds measure mass. Pound-force (lbf) and newtons measure force — they are not interchangeable with kg.
