Convert Millicuries to Picocuries (mCi to pCi)
1 millicurie (mCi) = 1000000000 picocuries (pCi). 1 pCi = 1 × 10⁻⁹ mCi. Example: 15 mCi = 15 × 1000000000 = 15000000000 pCi.

How to Convert Millicurie to Picocurie
- 1 mCi = 1000000000 pCi
- 1 pCi = 1 × 10⁻⁹ mCi
- Example: convert 15 mCi to pCi: 15 mCi = 15 × 1000000000 pCi = 15000000000 pCi
Formula
pCi = mCi × 1000000000
Derivation from SI units:
- 1 mCi = 3.7 × 10⁷ Bq = 37 MBq.
- 1 pCi = 0.037 Bq.
- 1 mCi = 37000000 Bq ÷ 0.037 Bq per pCi = 1000000000 pCi
Both units are defined exactly, so the factor is exact. Millicurie definition: millicurie; Picocurie definition: picocurie.
Worked examples
- A reading of 15 mCi converts to 15000000000 pCi.
15 mCi × 1000000000 = 15000000000 pCi - A value of 30 mCi is 30000000000 pCi.
30 mCi × 1000000000 = 30000000000 pCi

Where it's used
Millicuries are used for US radiopharmaceutical doses (e.g. 10 mCi FDG), while picocuries appear in radon in homes (pCi/L). Both measure activity of a radioactive source, so the conversion is a fixed factor.
