Formula
kGy = cGy × 1e-5
Multiply any value in centigrays by 1e-5 to obtain the value in kilograys.
Worked example
Convert 100000 cGy to kGy.
- 01Start with 100000 cGy.
- 02Multiply by the conversion factor: 100000 × 1e-5 = 1 kGy.
Result100000 cGy = 1 kGy

FAQ
What is the conversion factor from cGy to kGy?
1 cGy equals 1e-5 kGy. To convert, multiply the value in centigrays by 1e-5.
How do I convert 1 cGy to kGy?
1 cGy = 1e-5 kGy. For any value, multiply by 1e-5.
How do I convert kGy back to cGy?
Divide by the same factor — or equivalently, multiply by 100000. So 1 kGy = 100000 cGy.
When would I need to convert centigray to kilogray?
Radiation absorbed-dose conversions between cGy 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).
