Convert microsieverts to millirems
1 µSv = 0.1 mrem — exactly. Both units are defined against the SI, so this factor is a fraction, not an approximation.
0.1mrem
As a fraction: 1/10
1 µSv = 0.1 mrem
How to convert microsieverts to millirems
Multiply the number of microsieverts by 0.1 to get millirems.
The exact factor is 0.1 — as a fraction, 1/10.
Millirem: A chest X-ray is roughly 10 mrem, i.e. 0.1 mSv.
