How to Convert Centigrays to Kilograys
The centigray and kilogray are both units of radiation dose. By definition, 1 kilogray equals exactly 100000 centigrays. This means to convert centigrays to kilograys, you divide by 100000.
Formula
Step-by-Step Example
Convert 5 cGy to kilograys:
We need to convert centigrays to kilograys
Since 1 kGy = 100000 cGy, divide by 100000
5 ÷ 100000 = 5e-5
5 cGy = 5e-5 kGy
