Convert Megabecquerels to Kilobecquerels (MBq to kBq)
1 megabecquerel (MBq) = 1000 kilobecquerels (kBq). 1 kBq = 0.001 MBq. Example: 15 MBq = 15 × 1000 = 15000 kBq.

How to Convert Megabecquerel to Kilobecquerel
- 1 MBq = 1000 kBq
- 1 kBq = 0.001 MBq
- Example: convert 15 MBq to kBq: 15 MBq = 15 × 1000 kBq = 15000 kBq
Formula
kBq = MBq × 1000
Derivation from SI units:
- 1 MBq = 10⁶ Bq.
- 1 kBq = 10³ Bq.
- 1 MBq = 1000000 Bq ÷ 1000 Bq per kBq = 1000 kBq
Both units are defined exactly, so the factor is exact. Megabecquerel definition: megabecquerel; Kilobecquerel definition: kilobecquerel.
Worked examples
- A reading of 370 MBq converts to 370000 kBq.
370 MBq × 1000 = 370000 kBq - A value of 740 MBq is 740000 kBq.
740 MBq × 1000 = 740000 kBq

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