Formula: rad = mrad × 0.001
Reverse: mrad = rad × 1,000
Step-by-Step Example
- Start with your value in Millirad. For example: 5 mrad
- Multiply by the conversion factor: 5 x 0.001
- The result is: 0.005 rad
About Millirad
The millirad (mrad) is a unit of radiation dose. One millirad 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.
