Convert Centigrams to Tonnes
1 centigram is 1.00e-8 t. One centigram is exactly 1e-8 tonnes.
One centigram is 1.0000 × 10^-8 tonnes. To convert centigrams to tonnes, multiply by 1.0000 × 10^-8; to go the other way, divide by 1.0000 × 10^-8 or multiply by 100000000. 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. A hundredth of a gram, or ten milligrams.

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 centigrams to tonnes? The converter and the working
- 1.Take the measurement in centigrams.
- 2.Multiply by 1.0000 × 10^-8 — that is how many tonnes fit in one centigram.
- 3.To go back the other way, divide by 1.0000 × 10^-8, or multiply by 100000000.
Worked example: 25 centigrams to tonnes
- Formula
- cg × 1.0000 × 10^-8 = t
- Arithmetic
- 25 × 1.0000 × 10^-8 = 2.50e-7 t
- Answer
- 25 cg = 2.50e-7 t
The factor is rounded for display; the figure above is computed from the full value.

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