Formula
mrad = cGy × 1000
Multiply any value in centigrays by 1000 to obtain the value in millirads.
Worked example
Convert 1 cGy to mrad.
- 01Start with 1 cGy.
- 02Multiply by the conversion factor: 1 × 1000 = 1000 mrad.
Result1 cGy = 1000 mrad

FAQ
What is the conversion factor from cGy to mrad?
1 cGy equals 1000 mrad. To convert, multiply the value in centigrays by 1000.
How do I convert 1 cGy to mrad?
1 cGy = 1000 mrad. For any value, multiply by 1000.
How do I convert mrad back to cGy?
Divide by the same factor — or equivalently, multiply by 0.001. So 1 mrad = 0.001 cGy.
When would I need to convert centigray to millirad?
Radiation absorbed-dose conversions between cGy and mrad 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).
