Microcuries to Curies
1 µCi = 0.000001 Ci. Edit either value to convert instantly.
Conversion formula
Ci = µCi × (37,000) × (1 / 3.7 × 10¹⁰)1 µCi = 0.000001 Ci
microcurie (µCi)
microcurie is a unit of radioactivity: 1 µCi = 37,000 Bq. Activity measures nuclear transformations per time: 1 Bq = 1 transformation per second; it does not measure absorbed dose.
