Formula
Step-by-Step Example
Convert 5 mCi to gigabecquerels:
We need to convert millicuries to gigabecquerels
Since 1 mCi = 37000000 GBq, multiply by 37000000
5 × 37000000 = 185000000
5 mCi = 185000000 GBq

About These Units
Millicurie (mCi)
A millicurie (mCi) equals 0.001 curie or 37 MBq. Standard unit for nuclear medicine imaging in US: thyroid uptake 0.1-0.2 mCi, bone scan 20-30 mCi, cardiac stress test 25-35 mCi. Laboratory calibration sources: 1-10 mCi typical.
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.
