How to Convert Millirem to Microsievert
To convert from Millirem (mrem) to Microsievert (µSv), multiply the value by 10.
Formula: µSv = mrem × 10
Reverse: mrem = µSv × 0.1
Step-by-Step Example
- Start with your value in Millirem. For example: 5 mrem
- Multiply by the conversion factor: 5 x 10
- The result is: 50 µSv
About Millirem
The millirem (mrem) is a unit of radiation dose. One millirem equals 1.000000 × 10^-5 grays. UnitConvertLab converts it against every other radiation unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.
Common uses: radiation calculations, engineering and science, education.
About Microsievert
The microsievert (µSv) is a unit of radiation dose. One microsievert equals 1.000000 × 10^-6 grays. UnitConvertLab converts it against every other radiation unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.
Common uses: radiation calculations, engineering and science, education.
