Formula
Formula
μGy = nGy × 0.001
Multiply any value in nanograys by 0.001 to obtain the value in micrograys.
Worked example
Convert 1000 nGy to μGy.
- 01Start with 1000 nGy.
- 02Multiply by the conversion factor: 1000 × 0.001 = 1 μGy.
Result1000 nGy = 1 μGy

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