How do you convert tonnes to slugs? The converter and the working
- 1.Take the measurement in tonnes.
- 2.Multiply by 68.521766 — that is how many slugs fit in one tonne.
- 3.To go back the other way, divide by 68.521766, or multiply by 0.014593903.
Worked example: 25 tonnes to slugs
- Formula
- t × 68.521766 = slug
- Arithmetic
- 25 × 68.521766 = 1,713.04 slug
- Answer
- 25 t = 1,713.04 slug
The factor is rounded for display; the figure above is computed from the full value.

What is a tonne?
One thousand kilograms, also called the metric ton — 2,204.6 pounds.
What is a slug?
The mass that one pound-force accelerates at one foot per second squared — 32.174 pounds. It exists so that F = ma works in US customary units without a conversion constant, and it is why American engineering statics is not simply pounds.
How many slugs are in a tonne?
One tonne is 68.521766 slugs. Going the other way, one slug is 0.014593903 tonnes. 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.
