Curies to gigabecquerels
Type a value in Ci to get it in GBq instantly.
3,700GBq
That's 100× as active as a gram of radium — nothing on our list beats it. That is 3.7×10¹² atoms decaying every second.
Convert the other way: GBq to Ci
What it means
How active is that?
Activity counts decays; it says nothing about the dose received, which depends on the radiation type and distance.
The math
How to convert Ci to GBq
To convert curies to gigabecquerels, multiply by 37.
Example: 100 Ci × 37 = 3,700 GBq.
In the other direction, 1 GBq = 0.027027 Ci.
