Convert Micrograms to Tonnes
1 microgram is 0 t. One microgram is exactly 1e-12 tonnes.
One microgram is 1.0000 × 10^-12 tonnes. To convert micrograms to tonnes, multiply by 1.0000 × 10^-12; to go the other way, divide by 1.0000 × 10^-12 or multiply by 1000000000000. The factor is exact rather than rounded: it follows from NIST Handbook 44. One millionth of a gram.

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 micrograms to tonnes?
- 1.Take the measurement in micrograms.
- 2.Multiply by 1.0000 × 10^-12 — that is how many tonnes fit in one microgram.
- 3.To go back the other way, divide by 1.0000 × 10^-12, or multiply by 1000000000000.

What are micrograms and tonnes?
- Microgram (mcg)
- One millionth of a gram. Written mcg rather than µg on labels deliberately: the Greek letter is the character most often lost in transcription, and a factor of a thousand in a dose is not a rounding error.
- Tonne (t)
- One thousand kilograms, also called the metric ton — 2,204.6 pounds.
Questions people actually ask
- How many tonnes are in a microgram?
- 1.0000 × 10^-12. One thousand kilograms, also called the metric ton — 2,204.6 pounds.
- How do I convert tonnes back to micrograms?
- Divide by 1.0000 × 10^-12, or multiply by 1000000000000 — they are the same operation.
