How to Convert Milligray to Microsievert
To convert from Milligray (mGy) to Microsievert (µSv), multiply the value by 1,000.
Formula: µSv = mGy × 1,000
Reverse: mGy = µSv × 0.001
Step-by-Step Example
- Start with your value in Milligray. For example: 5 mGy
- Multiply by the conversion factor: 5 x 1,000
- The result is: 5,000 µSv
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 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.
