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