All four units describe the same mass; the pound used here is the international avoirdupois pound.
Convert the source value to kilograms, then divide by the target unit's kilogram factor: target = value × source factor ÷ target factor.
| Unit | Kilograms per unit |
|---|---|
| Kilogram (kg) | 1 |
| Gram (g) | 0.001 |
| Pound (lb) | 0.45359237 |
| Ounce (oz) | 0.028349523125 |
The pound factor is exact by international agreement: 1 lb = 0.45359237 kg. The ounce is 1/16 of that pound.
1 kg ÷ 0.45359237 kg/lb = 2.204623 lb, and 1 kg ÷ 0.028349523125 kg/oz = 35.273962 oz. A 70 kg person is 70 ÷ 0.45359237 = 154.323584 lb.
Negative weights are rejected as invalid. Display values are rounded to 6 decimal places; the underlying calculation is not rounded. This page uses avoirdupois pounds and ounces (the everyday US/UK system), not troy units used for precious metals.
1 kg = 2.20462262185 lb, shown as 2.204623 after display rounding.
No. Gold uses troy pounds and troy ounces, which differ. This page uses the avoirdupois pound for everyday weights.
16 ounces = 1 pound, exactly.
So small conversions (for example grams to ounces) stay readable without hiding the underlying precision.
Not directly: 1 stone = 14 lb = 6.35029318 kg. Convert stones to kilograms first and enter that value.
