Convert Picocuries to Megabecquerels (pCi to MBq)
1 picocurie (pCi) = 3.7 × 10⁻⁸ megabecquerels (MBq). 1 MBq = 27027027.03 pCi. Example: 15 pCi = 15 × 3.7 × 10⁻⁸ = 5.55 × 10⁻⁷ MBq.

How to Convert Picocurie to Megabecquerel
- 1 pCi = 3.7 × 10⁻⁸ MBq
- 1 MBq = 27027027.03 pCi
- Example: convert 15 pCi to MBq: 15 pCi = 15 × 3.7 × 10⁻⁸ MBq = 5.55 × 10⁻⁷ MBq
Formula
MBq = pCi × 3.7 × 10⁻⁸
or MBq = pCi ÷ 27027027.02703
Derivation from SI units:
- 1 pCi = 0.037 Bq.
- 1 MBq = 10⁶ Bq.
- 1 pCi = 0.037 Bq ÷ 1000000 Bq per MBq = 3.7 × 10⁻⁸ MBq
Both units are defined exactly, so the factor is exact. Picocurie definition: picocurie; Megabecquerel definition: megabecquerel.
Worked examples
- A reading of 4 pCi converts to 1.48 × 10⁻⁷ MBq.
4 pCi × 3.7 × 10⁻⁸ = 1.48 × 10⁻⁷ MBq - A value of 20 pCi is 7.4 × 10⁻⁷ MBq.
20 pCi × 3.7 × 10⁻⁸ = 7.4 × 10⁻⁷ MBq

Where it's used
Picocuries are used for radon in homes (pCi/L), while megabecquerels appear in PET and SPECT doses (e.g. 370 MBq of F-18 FDG). Both measure activity of a radioactive source, so the conversion is a fixed factor.
