Convert Kilobecquerels to Megabecquerels (kBq to MBq)
1 kilobecquerel (kBq) = 0.001 megabecquerels (MBq). 1 MBq = 1000 kBq. Example: 15 kBq = 15 × 0.001 = 0.015 MBq.

How to Convert Kilobecquerel to Megabecquerel
- 1 kBq = 0.001 MBq
- 1 MBq = 1000 kBq
- Example: convert 15 kBq to MBq: 15 kBq = 15 × 0.001 MBq = 0.015 MBq
Formula
MBq = kBq ÷ 1000
Derivation from SI units:
- 1 kBq = 10³ Bq.
- 1 MBq = 10⁶ Bq.
- 1 kBq = 1000 Bq ÷ 1000000 Bq per MBq = 0.001 MBq
Both units are defined exactly, so the factor is exact. Kilobecquerel definition: kilobecquerel; Megabecquerel definition: megabecquerel.
Worked examples
- A reading of 2 kBq converts to 0.002 MBq.
2 kBq × 0.001 = 0.002 MBq - A value of 20 kBq is 0.02 MBq.
20 kBq × 0.001 = 0.02 MBq

Where it's used
Kilobecquerels are used for laboratory sources and calibration standards, 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 kilobecquerel?
1 kBq = 0.001 MBq.
How do I convert kilobecquerels to megabecquerels?
Multiply the value in kBq by 0.001, or divide it by 1000. For example, 15 kBq × 0.001 = 0.015 MBq.
Is the kBq to MBq conversion exact?
Yes. Both units are defined exactly, and 1 kBq is exactly 0.001 MBq.
