Formula
Formula
mrad = nGy × 0.0001
Multiply any value in nanograys by 0.0001 to obtain the value in millirads.
Worked example
Convert 1.00000e+6 nGy to mrad.
- 01Start with 1.00000e+6 nGy.
- 02Multiply by the conversion factor: 1.00000e+6 × 0.0001 = 100 mrad.
Result1.00000e+6 nGy = 100 mrad

FAQ
What is the conversion factor from nGy to mrad?
1 nGy equals 0.0001 mrad. To convert, multiply the value in nanograys by 0.0001.
How do I convert 1 nGy to mrad?
1 nGy = 0.0001 mrad. For any value, multiply by 0.0001.
How do I convert mrad back to nGy?
Divide by the same factor — or equivalently, multiply by 10000. So 1 mrad = 10000 nGy.
When would I need to convert nanogray to millirad?
Radiation absorbed-dose conversions between nGy 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).
