Formula
Formula
krad = Gy × 0.1
Multiply any value in grays by 0.1 to obtain the value in kilorads.
Worked example
Convert 10 Gy to krad.
- 01Start with 10 Gy.
- 02Multiply by the conversion factor: 10 × 0.1 = 1 krad.
Result10 Gy = 1 krad

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