Stone (st) — an imperial unit of mass equal to 14 pounds
It is defined as exactly 14 avoirdupois pounds; since 1 lb = 0.45359237 kg exactly, 1 st = 6.35029318 kg exactly. Used mainly in the United Kingdom and Ireland for measuring human body weight.
- Symbol: st
- System: Imperial unit for mass
- Exact relations: 1 st = 14 lb = 224 oz = 6.35029318 kg
- Metric equivalents: 1 st ≈ 6.35029 kg ≈ 6350.29 g
- Typical examples: a person weighing 10 st is 140 lb; a small adult ~8 st; a larger adult ~15 st.
Gram (g) — a common SI unit of mass
It is defined as one thousandth of a kilogram, the SI base unit for mass; the kilogram is defined by fixing the Planck constant at exactly 6.62607015×10⁻³⁴ J·s. Used worldwide for measuring small amounts of mass in science, cooking, nutrition, medicine, commerce, and everyday life.
- Symbol: g
- System: SI unit for mass; decimal submultiple of the kilogram
- Exact relations: 1 g = 0.001 kg = 1000 mg
- Imperial equivalents (derived from 1 lb = 0.45359237 kg exactly): 1 g ≈ 0.03527396 oz ≈ 0.00220462 lb
- Typical examples: a paperclip ~1 g; a teaspoon of sugar ~4 g; a chocolate bar ~50 g.
