1 stone (st) equals exactly 0.00625 UK long tons (L/T). Use the formula: st × 0.00625 = L/T.
To convert stone to UK long tons, multiply your value in stone by 0.00625. For example, 5 st × 0.00625 = 0.03124998 L/T.
100 stone = 0.62499963 UK long tons. Calculation: 100 × 0.00625 = 0.62499963.
To convert UK long tons back to stone, divide by 0.00625 (or multiply by 160.0001). Example: 10 L/T ÷ 0.00625 = 1600.0009 st.
Yes. This converter uses the internationally recognised exact conversion factor: 1 st = 0.00625 L/T. All calculations are performed in your browser with no rounding until display.
10 stone = 0.06249996 UK long tons. Simply multiply by 0.00625.
Converting stone to UK long tons is commonly needed for freight logistics, commodity trading, construction material procurement, and agricultural reporting where one system uses st and another uses L/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 UK long ton (symbol L/T, also "imperial ton" or "gross ton") equals 2,240 avoirdupois pounds or 1,016.0469088 kilograms. Used in Britain for coal and shipping, it is slightly larger than both the US short ton (2,000 lb) and the metric ton (1,000 kg). Britain adopted metric units in 1965 and the long ton is no longer used in new UK trade contracts, though it appears in historical records.
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 long ton traces to medieval England, where a "wine tun" was a large barrel of ~252 gallons. A standard ship's cargo unit ("ton burden") evolved into a 2,240-pound standard because 2,240 lb = 20 hundredweight (each of 112 lb) — convenient for counting by the hundredweight. The Coal Industry Act 1831 formalised the long ton for coal. British Overseas Territories and some US steel industry sectors still use it.
Interesting fact: HMS Victory, Nelson's flagship at Trafalgar (1805), was rated at 2,162 long tons displacement. Modern international shipping uses metric tons (deadweight tonnage), but engineers working with pre-1965 British specifications regularly need long ton conversions.
