Convert Long tons to Tonnes
1 long ton is 1.02 t. One long ton is exactly 1.0160469088 tonnes.
One long ton is 1.0160469 tonnes. To convert long tons to tonnes, multiply by 1.0160469; to go the other way, divide by 1.0160469 or multiply by 0.98420653. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST Handbook 44. The British ton: 2,240 lb, against the US short ton’s 2,000 and the tonne’s 2,204.62.

Factors are entered by hand from NIST Handbook 44 rather than derived from a units library, so the ones that terminate are exact rather than rounded.
How do you convert long tons to tonnes? The converter and the working
- 1.Take the measurement in long tons.
- 2.Multiply by 1.0160469 — that is how many tonnes fit in one long ton.
- 3.To go back the other way, divide by 1.0160469, or multiply by 0.98420653.
Worked example: 25 long tons to tonnes
- Formula
- LT × 1.0160469 = t
- Arithmetic
- 25 × 1.0160469 = 25.4 t
- Answer
- 25 LT = 25.4 t
The factor is rounded for display; the figure above is computed from the full value.
