Convert Tonnes to Micrograms

1 tonne is 1,000,000,000,000 mcg. One tonne is exactly 1000000000000 micrograms.

One tonne is 1000000000000 micrograms. To convert tonnes to micrograms, multiply by 1000000000000; to go the other way, divide by 1000000000000 or multiply by 1.0000 × 10^-12. 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.

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 tonnes to micrograms?

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

What are tonnes and micrograms?

Tonne (t)
One thousand kilograms, also called the metric ton — 2,204.6 pounds.
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.

Questions people actually ask

How many micrograms are in a tonne?
1000000000000. 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.
How do I convert micrograms back to tonnes?
Divide by 1000000000000, or multiply by 1.0000 × 10^-12 — they are the same operation.
