How to Convert Milligray to Rad

To convert from Milligray (mGy) to Rad (rad), multiply the value by 0.1.

Formula: rad = mGy × 0.1

Reverse: mGy = rad × 10

Step-by-Step Example

Start with your value in Milligray. For example: 5 mGy
Multiply by the conversion factor: 5 x 0.1
The result is: 0.5 rad

About Milligray

The milligray (mGy) is a unit of radiation dose. One milligray equals 0.001 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.
