Curie to microcurie Conversion
1 curie (Ci) is equal to 1000000 microcurie (µCi).
1 Ci = 1000000 µCi
or
1 µCi = 0.000001 Ci
Formula
To convert a radioactivity from curie (Ci) to microcurie (µCi), multiply the radioactivity in curie by 1000000
r(µCi) = r(Ci) × 1000000
Examples:
Convert 500 curie to microcurie:
r(µCi) = 500Ci × 1000000 = 500000000 µCi
