Convert Becquerels to Megabecquerels (Bq to MBq)
1 becquerel (Bq) = 0.000001 megabecquerels (MBq). 1 MBq = 1000000 Bq. Example: 15 Bq = 15 × 0.000001 = 0.000015 MBq.

How to Convert Becquerel to Megabecquerel
- 1 Bq = 0.000001 MBq
- 1 MBq = 1000000 Bq
- Example: convert 15 Bq to MBq: 15 Bq = 15 × 0.000001 MBq = 0.000015 MBq
Formula
MBq = Bq ÷ 1000000
Derivation from SI units:
- 1 Bq = 1 decay per second (s⁻¹).
- 1 MBq = 10⁶ Bq.
Both units are defined exactly, so the factor is exact. Becquerel definition: becquerel; Megabecquerel definition: megabecquerel.
Worked examples
- A reading of 100 Bq converts to 0.0001 MBq.
100 Bq × 0.000001 = 0.0001 MBq - A value of 3700 Bq is 0.0037 MBq.
3700 Bq × 0.000001 = 0.0037 MBq

Where it's used
Becquerels are used for food and environmental radioactivity limits, 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.

Frequently asked questions
How many megabecquerels are in 1 becquerel?
1 Bq = 0.000001 MBq.
How do I convert becquerels to megabecquerels?
Multiply the value in Bq by 0.000001, or divide it by 1000000. For example, 15 Bq × 0.000001 = 0.000015 MBq.
Is the Bq to MBq conversion exact?
Yes. Both units are defined exactly, and 1 Bq is exactly 0.000001 MBq.
