1 stone (st) equals exactly 6350.29 grams (g). Use the formula: st × 6350.29 = g.
To convert stone to grams, multiply your value in stone by 6350.29. For example, 5 st × 6350.29 = 31751.45 g.
100 stone = 635029 grams. Calculation: 100 × 6350.29 = 635029.
To convert grams back to stone, divide by 6350.29 (or multiply by 0.00015747). Example: 10 g ÷ 6350.29 = 0.00157473 st.
Yes. This converter uses the internationally recognised exact conversion factor: 1 st = 6350.29 g. All calculations are performed in your browser with no rounding until display.
10 stone = 63502.9 grams. Simply multiply by 6350.29.
Converting stone to grams is commonly needed for everyday tasks like cooking recipes, body weight tracking, shopping internationally, or shipping parcels where one system uses st and another uses g.
The stone (st) is a British imperial unit of mass equal to exactly 14 avoirdupois pounds or 6.35029318 kilograms. Used almost exclusively in the United Kingdom and Ireland for human body weight, it has no role in scientific, commercial, or international contexts. The stone is not an SI unit and was removed from official UK trade measurement in 1985, though it remains deeply embedded in everyday British culture.
The gram (g) is a unit of mass in the metric system equal to one-thousandth of a kilogram (0.001 kg). While the kilogram is the SI base unit, the gram is the practical everyday unit for small masses in cooking, pharmacy, chemistry, and nutrition labelling. The word derives from Late Latin gramma (small weight), itself from Greek.
One of the oldest English weight units, the stone was referenced as early as the 13th century. Historically its value varied by commodity (8 lb for meat, 12 lb for hemp, 14 lb for wool, 16 lb for glass). King Edward III standardised the wool stone at 14 pounds in 1350, which became the universal English standard. The Weights and Measures Act 1835 formally defined the stone as 14 lb. EU harmonisation abolished the stone for trade in 1985.
Interesting fact: The world record heaviest person weighed 635 kg — exactly 100 stone, illustrating how the stone unit provides digestible reference points for large body weights. British people typically express their weight as, for example, "11 stone 4 pounds."
Defined in 1795 by the French Academy of Sciences as the mass of one cubic centimetre of pure water at 4 °C — this made 1 mL of water weigh almost exactly 1 gram. The gram was the practical base of early metric calculations before the kilogram took over as SI base unit in 1875. The relationship 1 mL water ≈ 1 g is still a useful approximation in cooking and chemistry.
Interesting fact: A standard large paperclip weighs about 1 gram. The gram forms the basis for milligram (mg), microgram (μg), and tonne (10⁶ g) through SI prefixes.
