Convert Microcuries to Megabecquerels (µCi to MBq)
1 microcurie (µCi) = 0.037 megabecquerels (MBq). 1 MBq = 27.02702703 µCi. Example: 15 µCi = 15 × 0.037 = 0.555 MBq.

How to Convert Microcurie to Megabecquerel
- 1 µCi = 0.037 MBq
- 1 MBq = 27.02702703 µCi
- Example: convert 15 µCi to MBq: 15 µCi = 15 × 0.037 MBq = 0.555 MBq
Formula
MBq = µCi × 0.037
or MBq = µCi ÷ 27.02702702703
Derivation from SI units:
- 1 µCi = 3.7 × 10⁴ Bq = 37 kBq.
- 1 MBq = 10⁶ Bq.
- 1 µCi = 37000 Bq ÷ 1000000 Bq per MBq = 0.037 MBq
Both units are defined exactly, so the factor is exact. Microcurie definition: microcurie; Megabecquerel definition: megabecquerel.
Worked examples
- A reading of 2 µCi converts to 0.074 MBq.
2 µCi × 0.037 = 0.074 MBq - A value of 20 µCi is 0.74 MBq.
20 µCi × 0.037 = 0.74 MBq

Where it's used
Microcuries are used for check and calibration sources, 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.
