Convert Long tons to Kilograms

1 long ton is 1,016.05 kg. One long ton is exactly 1016.0469088 kilograms.

One long ton is 1016.0469 kilograms. To convert long tons to kilograms, multiply by 1016.0469; to go the other way, divide by 1016.0469 or multiply by 9.8421 × 10^-4. 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 kilograms? The converter and the working

  1. 1.Take the measurement in long tons.
  2. 2.Multiply by 1016.0469 — that is how many kilograms fit in one long ton.
  3. 3.To go back the other way, divide by 1016.0469, or multiply by 9.8421 × 10^-4.

Worked example: 25 long tons to kilograms

Formula
LT × 1016.0469 = kg
Arithmetic
25 × 1016.0469 = 25,401.17 kg
Answer
25 LT = 25,401.17 kg

The factor is rounded for display; the figure above is computed from the full value.

What is a long ton?

The British ton: 2,240 lb, against the US short ton’s 2,000 and the tonne’s 2,204.62. Three units, one word, and shipping documents use all three.

What is a kilogram?

The SI base unit of mass, defined since 2019 by fixing the Planck constant rather than by a metal cylinder in Paris.

How many kilograms are in a long ton?

One long ton is 1016.0469 kilograms. Going the other way, one kilogram is 9.8421 × 10^-4 long tons. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.

Every weight unit here

The whole group — 15 units with their symbols and the size of each one in kilograms — is on the conversion index, along with every pair it makes. The table above already gives each of them relative to a long ton.
