FAQ
What is the conversion factor from krad to kGy?
1 krad equals 0.01 kGy. To convert, multiply the value in kilorads by 0.01.
How do I convert 1 krad to kGy?
1 krad = 0.01 kGy. For any value, multiply by 0.01.
How do I convert kGy back to krad?
Divide by the same factor — or equivalently, multiply by 100. So 1 kGy = 100 krad.
When would I need to convert kilorad to kilogray?
Radiation absorbed-dose conversions between krad and kGy 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).
