1 stone (st) equals exactly 0.00635029 metric tons (t). Use the formula: st × 0.00635029 = t.
To convert stone to metric tons, multiply your value in stone by 0.00635029. For example, 5 st × 0.00635029 = 0.03175145 t.
100 stone = 0.635029 metric tons. Calculation: 100 × 0.00635029 = 0.635029.
To convert metric tons back to stone, divide by 0.00635029 (or multiply by 157.4731). Example: 10 t ÷ 0.00635029 = 1574.7312 st.
Yes. This converter uses the internationally recognised exact conversion factor: 1 st = 0.00635029 t. All calculations are performed in your browser with no rounding until display.
10 stone = 0.0635029 metric tons. Simply multiply by 0.00635029.
Converting stone to metric tons is commonly needed for freight logistics, commodity trading, construction material procurement, and agricultural reporting where one system uses st and another uses t.
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 metric ton (tonne, symbol t) equals exactly 1,000 kilograms or 1,000,000 grams. Not an SI unit but derived from the kilogram, it is used globally for large-scale measurements in shipping, agriculture, mining, and manufacturing. In the US, "metric ton" or "tonne" distinguishes it from the US short ton (2,000 lb ≈ 907 kg) and UK long ton (2,240 lb ≈ 1,016 kg).
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."
The tonne was introduced alongside the metric system in late 18th-century France and incorporated into the International System as an accepted non-SI unit. Its name (with final "e") was adopted to avoid confusion with British and American ton units. As international trade standardised on metric units through the 20th century, the metric ton became the global benchmark for commodity markets in grain, oil, steel, and other bulk goods.
Interesting fact: A standard ISO shipping container (20-foot TEU) can carry approximately 21–24 metric tons of cargo. The global annual steel production is about 1.9 billion metric tons — roughly 240 kg for every person on Earth.
