Formula
Formula
MBq = kBq × 0.001
Multiply any value in kilobecquerels by 0.001 to obtain the value in megabecquerels.
Worked example
Convert 1000 kBq to MBq.
- 01Start with 1000 kBq.
- 02Multiply by the conversion factor: 1000 × 0.001 = 1 MBq.
Result1000 kBq = 1 MBq

FAQ
What is the conversion factor from kBq to MBq?
1 kBq equals 0.001 MBq. To convert, multiply the value in kilobecquerels by 0.001.
How do I convert 1 kBq to MBq?
1 kBq = 0.001 MBq. For any value, multiply by 0.001.
How do I convert MBq back to kBq?
Divide by the same factor — or equivalently, multiply by 1000. So 1 MBq = 1000 kBq.
When would I need to convert kilobecquerel to megabecquerel?
Radioactivity (activity) conversions between kBq and MBq are routine in health physics, nuclear medicine ordering, environmental monitoring, radiopharmacy and reactor/accelerator-source documentation. The becquerel (Bq) is the SI unit; the curie (Ci) is the legacy unit (1 Ci ≡ 3.7×10¹⁰ Bq exactly). This category is strictly activity (decays per second) — it does NOT cover absorbed dose (Gy, rad), dose equivalent (Sv, rem), exposure or dose rate, all of which are different physical quantities and live in separate categories.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
