Convert Microcuries to Picocuries (µCi to pCi)
1 microcurie (µCi) = 1000000 picocuries (pCi). 1 pCi = 0.000001 µCi. Example: 15 µCi = 15 × 1000000 = 15000000 pCi.

How to Convert Microcurie to Picocurie
- 1 µCi = 1000000 pCi
- 1 pCi = 0.000001 µCi
- Example: convert 15 µCi to pCi: 15 µCi = 15 × 1000000 pCi = 15000000 pCi
Formula
pCi = µCi × 1000000
Derivation from SI units:
- 1 µCi = 3.7 × 10⁴ Bq = 37 kBq.
- 1 pCi = 0.037 Bq.
- 1 µCi = 37000 Bq ÷ 0.037 Bq per pCi = 1000000 pCi
Both units are defined exactly, so the factor is exact. Microcurie definition: microcurie; Picocurie definition: picocurie.
Worked examples
- A reading of 2 µCi converts to 2000000 pCi.
2 µCi × 1000000 = 2000000 pCi - A value of 20 µCi is 20000000 pCi.
20 µCi × 1000000 = 20000000 pCi

Where it's used
Microcuries are used for check and calibration sources, while picocuries appear in radon in homes (pCi/L). Both measure activity of a radioactive source, so the conversion is a fixed factor.
