How it works
Each unit is stored as an exact number of kilograms:
result = value × from-unit (kg) ÷ to-unit (kg)
- 1 pound (lb) = 0.45359237 kg exactly
- 1 ounce (oz) = 1/16 lb = 28.349523125 g
- 1 stone (st) = 14 lb = 6.35029318 kg
- 1 short ton (US) = 2,000 lb; 1 long ton (UK) = 2,240 lb; 1 metric ton = 1,000 kg
- 1 carat = 200 mg

Weight or mass?
Strictly speaking, kilograms and pounds measure mass, the amount of matter in an object. Weight is the force gravity puts on that mass. On Earth the two are used interchangeably, and every scale shows mass, so this converter calls it weight like everyone else does.
Ounces here are avoirdupois ounces, the ones used for food and body weight. Precious metals use the troy ounce (31.1035 g), which is about 10% heavier.
Limitations
- Troy ounces and pounds (for gold and silver) are not included.
- Weight can't be negative.
- Results are rounded for display to at least 6 significant digits.
