FAQ
What is the conversion factor from krad to Gy?
1 krad equals 10 Gy. To convert, multiply the value in kilorads by 10.
How do I convert 1 krad to Gy?
1 krad = 10 Gy. For any value, multiply by 10.
How do I convert Gy back to krad?
Divide by the same factor — or equivalently, multiply by 0.1. So 1 Gy = 0.1 krad.
When would I need to convert kilorad to gray?
Radiation absorbed-dose conversions between krad and Gy 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).
