Convert Millicurie to Kilocurie
Input the number of millicuries you want to convert to kilocuries.
How to Convert Millicuries to Kilocuries
The millicurie and kilocurie are both units of radioactivity. By definition, 1 millicurie equals exactly 1000 kilocuries. This means to convert millicuries to kilocuries, you multiply by 1000.
Formula
Step-by-Step Example
Convert 5 mCi to kilocuries:
We need to convert millicuries to kilocuries
Since 1 mCi = 1000 kCi, multiply by 1000
5 × 1000 = 5000
5 mCi = 5000 kCi

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.
Kilocurie (kCi)
A kilocurie (kCi) equals 1,000 curies or 37 TBq. Found in gamma irradiation facilities, high-level waste, and large medical sterilizers. Cobalt-60 panoramic irradiators: 0.5-2 MCi. Requires substantial shielding and remote handling.
