Convert Tonnes to Long tons
1 tonne is 0.98 LT. One tonne is exactly 0.984206527611 long tons.
One tonne is 0.98420653 long tons. To convert tonnes to long tons, multiply by 0.98420653; to go the other way, divide by 0.98420653 or multiply by 1.0160469. 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. One thousand kilograms, also called the metric ton — 2,204.6 pounds.

How do you convert tonnes to long tons? The converter and the working
- 1.Take the measurement in tonnes.
- 2.Multiply by 0.98420653 — that is how many long tons fit in one tonne.
- 3.To go back the other way, divide by 0.98420653, or multiply by 1.0160469.
Worked example: 25 tonnes to long tons
- Formula
- t × 0.98420653 = LT
- Arithmetic
- 25 × 0.98420653 = 24.61 LT
- Answer
- 25 t = 24.61 LT
The factor is rounded for display; the figure above is computed from the full value.
