Curies to Millicuries
1 Ci = 1,000 mCi. Edit either value to convert instantly.
Conversion formula
mCi = Ci × (3.7 × 10¹⁰) × (1 / 37,000,000)1 Ci = 1,000 mCi
curie (Ci)
curie is a unit of radioactivity: 1 Ci = 3.7 × 10¹⁰ Bq. Activity measures nuclear transformations per time: 1 Bq = 1 transformation per second; it does not measure absorbed dose.
