Formula: rad = mrem × 0.001
Reverse: mrem = rad × 1,000
Step-by-Step Example
- Start with your value in Millirem. For example: 5 mrem
- Multiply by the conversion factor: 5 x 0.001
- The result is: 0.005 rad
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 Rad
The rad is a non-SI unit of absorbed radiation dose. One rad is equal to 0.01 gray.
Common uses: legacy radiation monitoring, industrial radiation.
