Mathematical Facts
Convert stone to long ton with the formula below. long tn ≈ st × 0.00625. 1 st ≈ 6.35029318 kg; 1 long tn ≈ 1,016.0469088 kg A stone is a mass unit of 14 avoirdupois pounds. The result here is decimal stone, not a separate stone-and-pound pair. A long ton is 2240 avoirdupois pounds. An entry using this definition must remain distinct from both the US short ton and the metric ton.
Why This Conversion Matters
This pair is useful when a mass record uses stone and another record uses a different unit. Convert mixed stone-and-pound notation before entering a decimal value. Exact unit relationships: 1 st = 14 lb; 1 long tn = 2,240 lb. The calculator uses the full stored factor and rounds displayed results to 12 significant digits. Display precision is not a guarantee of measurement accuracy.
Real-World Examples
Decimal and mixed stone notation
A stone is a mass unit of 14 avoirdupois pounds. The result here is decimal stone, not a separate stone-and-pound pair. This pair is useful when a mass record uses stone and another record uses a different unit. Convert mixed stone-and-pound notation before entering a decimal value. The examples below are illustrative recorded masses, not standard product sizes or prescribed quantities.
Examples:
- Mass written in decimal stone: 2.5 st ≈ 0.015625 long tn
- Mass written in decimal stone: 7.25 st ≈ 0.0453125 long tn
Pro Tips:
- ✓For input, add pounds ÷ 14 to whole stones. For output, multiply the fractional stone by 14 to recover pounds.
Quick Reference Table
| stones | long tons |
|---|---|
| 10 st | 0.0625 LT |
| 50 st | 0.3125 LT |
| 100 st | 0.625 LT |
| 500 st | 3.125 LT |
| 1,000 st | 6.25 LT |
Formula: LT = st × conversion factor
Common Mistakes to Avoid
Reading 2.5 st as 2 st 5 lb
Half a stone is 7 lb, so 2.5 st equals 35 lb; 2 st 5 lb equals 33 lb. The notation error changes the mass by 2 lb.
✓ For input, add pounds ÷ 14 to whole stones. For output, multiply the fractional stone by 14 to recover pounds. 2.5 st ≈ 0.015625 long tn.
Pro Tips
- ✓For mixed notation, multiply the fractional stone by 14: 2.5 st means 2 st 7 lb.
- ✓Do not infer a long ton solely from a document’s country; check the unit named in the document.
- ✓For input, add pounds ÷ 14 to whole stones. For output, multiply the fractional stone by 14 to recover pounds.
