Gigabecquerels to curies
Type a value in GBq to get it in Ci instantly.
2.703Ci
That's 2.7× as active as a gram of radium — nothing on our list beats it. That is 1×10¹¹ atoms decaying every second.
Convert the other way: Ci to GBq
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 GBq to Ci
To convert gigabecquerels to curies, multiply by 0.027027.
Example: 100 GBq × 0.027027 = 2.7027 Ci.
In the other direction, 1 Ci = 37 GBq.
