Convert becquerels to gigabecquerels by entering a value below.
How to Convert Becquerels to Gigabecquerels
The becquerel and gigabecquerel are both units of radioactivity. By definition, 1 gigabecquerel equals exactly 1000000000 becquerels. This means to convert becquerels to gigabecquerels, you divide by 1000000000.
Formula
Step-by-Step Example
Convert 5 Bq to gigabecquerels:
We need to convert becquerels to gigabecquerels
Since 1 GBq = 1000000000 Bq, divide by 1000000000
5 ÷ 1000000000 = 5e-9
5 Bq = 5e-9 GBq

About These Units
Becquerel (Bq)
The becquerel (Bq) is the SI unit of radioactivity, measuring decay rate: one becquerel = one nuclear decay per second. Named after Henri Becquerel who discovered radioactivity in 1896. Human body contains ~7,000 Bq from potassium-40. One curie = 37 billion becquerels.
Gigabecquerel (GBq)
A gigabecquerel (GBq) equals 10⁹ becquerels or 27 millicuries. Used for cancer therapy doses (I-131: 3-7 GBq), industrial radiography sources (0.5-5 TBq), and brachytherapy seeds. Higher activity requires special handling.
