How to Convert Megabecquerels to Gigabecquerels
The megabecquerel and gigabecquerel are both units of radioactivity. By definition, 1 gigabecquerel equals exactly 1000 megabecquerels. This means to convert megabecquerels to gigabecquerels, you divide by 1000.
Formula
Step-by-Step Example
Convert 5 MBq to gigabecquerels:
We need to convert megabecquerels to gigabecquerels
Since 1 GBq = 1000 MBq, divide by 1000
5 ÷ 1000 = 0.005
5 MBq = 0.005 GBq
