Convert Megabecquerels to Becquerels (MBq to Bq)
1 megabecquerel (MBq) = 1000000 becquerels (Bq). 1 Bq = 0.000001 MBq. Example: 15 MBq = 15 × 1000000 = 15000000 Bq.

How to Convert Megabecquerel to Becquerel
- 1 MBq = 1000000 Bq
- 1 Bq = 0.000001 MBq
- Example: convert 15 MBq to Bq: 15 MBq = 15 × 1000000 Bq = 15000000 Bq
Formula
Bq = MBq × 1000000
Derivation from SI units:
- 1 MBq = 10⁶ Bq.
- 1 Bq = 1 decay per second (s⁻¹).
Both units are defined exactly, so the factor is exact. Megabecquerel definition: megabecquerel; Becquerel definition: becquerel.
Worked examples
- A reading of 370 MBq converts to 370000000 Bq.
370 MBq × 1000000 = 370000000 Bq - A value of 740 MBq is 740000000 Bq.
740 MBq × 1000000 = 740000000 Bq

Where it's used
Megabecquerels are used for PET and SPECT doses (e.g. 370 MBq of F-18 FDG), while becquerels appear in food and environmental radioactivity limits. Both measure activity of a radioactive source, so the conversion is a fixed factor.
