Formula
μGy = mGy × 1000
Multiply any value in milligrays by 1000 to obtain the value in micrograys.
Worked example
Convert 1 mGy to μGy.
- 01Start with 1 mGy.
- 02Multiply by the conversion factor: 1 × 1000 = 1000 μGy.
Result1 mGy = 1000 μGy

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