Curie to millicurie Conversion
1 curie (Ci) is equal to 1000 millicurie (mCi).
1 Ci = 1000 mCi
or
1 mCi = 0.001 Ci
Formula
To convert a radioactivity from curie (Ci) to millicurie (mCi), multiply the radioactivity in curie by 1000
r(mCi) = r(Ci) × 1000
Examples:
Convert 50 curie to millicurie:
r(mCi) = 50Ci × 1000 = 50000 mCi
