Convert micromoles to millimoles
1 µmol = 0.001 mmol — exactly. Both units are defined against the SI, so this factor is a fraction, not an approximation.
0.001mmol
As a fraction: 1/1000
1 µmol = 0.001 mmol
How to convert micromoles to millimoles
Multiply the number of micromoles by 0.001 to get millimoles.
The exact factor is 0.001 — as a fraction, 1/1000.
