Formula
Formula
rad = cGy × 1
Multiply any value in centigrays by 1 to obtain the value in rad (radiation absorbed dose).

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