Formula
How this is calculated
The avoirdupois ounce is the everyday ounce used for food, groceries and body weight in countries that still use imperial units. The conversion is exact because both units trace back to the 1959 international pound: one pound equals 0.45359237 kilograms exactly, and one pound contains exactly 16 ounces. Dividing through gives 1 oz = 0.45359237 ÷ 16 = 0.028349523125 kg exactly, so 1 kg = 35.27396195... oz.
To convert kilograms to ounces, multiply by 35.27396195. To go the other way, multiply ounces by 0.028349523125 (or equivalently 28.349523125 g/oz, then divide by 1000). Grams and pounds are derived from the same chain of exact definitions, so all four values shown are accurate to machine precision before any display rounding.
Note: this calculator uses the avoirdupois ounce, not the troy ounce (1 troy oz = 31.1034768 g), which is used only for precious metals. If you are converting gold or silver, you need the troy-ounce factor instead.
