Formula
Formula
mGy = mrad × 0.01
Multiply any value in millirads by 0.01 to obtain the value in milligrays.
Worked example
Convert 100 mrad to mGy.
- 01Start with 100 mrad.
- 02Multiply by the conversion factor: 100 × 0.01 = 1 mGy.
Result100 mrad = 1 mGy

FAQ
What is the conversion factor from mrad to mGy?
1 mrad equals 0.01 mGy. To convert, multiply the value in millirads by 0.01.
How do I convert 1 mrad to mGy?
1 mrad = 0.01 mGy. For any value, multiply by 0.01.
How do I convert mGy back to mrad?
Divide by the same factor — or equivalently, multiply by 100. So 1 mGy = 100 mrad.
When would I need to convert millirad to milligray?
Radiation absorbed-dose conversions between mrad and mGy are used in radiological protection, medical physics, and nuclear-industry health physics. Gray (Gy) is the SI standard; rad remains common in older US health-physics documentation (1 Gy = 100 rad).
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
