Convert Tonnes to Centigrams
1 tonne is 100,000,000 cg. One tonne is exactly 100000000 centigrams.
One tonne is 100000000 centigrams. To convert tonnes to centigrams, multiply by 100000000; to go the other way, divide by 100000000 or multiply by 1.0000 × 10^-8. The factor is exact rather than rounded: it follows from NIST Handbook 44. One thousand kilograms, also called the metric ton — 2,204.6 pounds.

How do you convert tonnes to centigrams? The converter and the working
- 1.Take the measurement in tonnes.
- 2.Multiply by 100000000 — that is how many centigrams fit in one tonne.
- 3.To go back the other way, divide by 100000000, or multiply by 1.0000 × 10^-8.
Worked example: 25 tonnes to centigrams
- Formula
- t × 100000000 = cg
- Arithmetic
- 25 × 100000000 = 2,500,000,000 cg
- Answer
- 25 t = 2,500,000,000 cg
The factor is exact, so this figure is exact too — only the display is rounded.

What is a tonne?
One thousand kilograms, also called the metric ton — 2,204.6 pounds.
What is a centigram?
A hundredth of a gram, or ten milligrams. It survives mainly in pharmacology and in school exercises about metric prefixes.
How many centigrams are in a tonne?
One tonne is 100000000 centigrams, exactly. Going the other way, one centigram is 1.0000 × 10^-8 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.
