mGytorad
Convert milligrays (mGy) to rad (radiation absorbed dose) (rad).
Factor1 mGy = 0.1 rad
Converter
mGy
Accepts numbers or expressions, e.g. 150 + 14.7
Result
rad
Rendered to 6 significant figures.
Formula
Formula
rad = mGy × 0.1
Multiply any value in milligrays by 0.1 to obtain the value in rad (radiation absorbed dose).
Worked example
Convert 10 mGy to rad.
- 01Start with 10 mGy.
- 02Multiply by the conversion factor: 10 × 0.1 = 1 rad.
Result10 mGy = 1 rad

FAQ
What is the conversion factor from mGy to rad?
1 mGy equals 0.1 rad. To convert, multiply the value in milligrays by 0.1.
How do I convert 1 mGy to rad?
1 mGy = 0.1 rad. For any value, multiply by 0.1.
How do I convert rad back to mGy?
Divide by the same factor — or equivalently, multiply by 10. So 1 rad = 10 mGy.
When would I need to convert milligray to rad (radiation absorbed dose)?
Radiation absorbed-dose conversions between mGy and rad 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).
