Formula
mGy = krad × 10000
Multiply any value in kilorads by 10000 to obtain the value in milligrays.
Worked example
Convert 1 krad to mGy.
- 01Start with 1 krad.
- 02Multiply by the conversion factor: 1 × 10000 = 10000 mGy.
Result1 krad = 10000 mGy

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