Formula
Formula
μGy = rad × 10000
Multiply any value in rad (radiation absorbed dose) by 10000 to obtain the value in micrograys.
Worked example
Convert 1 rad to μGy.
- 01Start with 1 rad.
- 02Multiply by the conversion factor: 1 × 10000 = 10000 μGy.
Result1 rad = 10000 μGy

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