Formula
Bq = MBq × 1000000
Multiply any value in megabecquerels by 1000000 to obtain the value in becquerels.
Worked example
Convert 1 MBq to Bq.
- 01Start with 1 MBq.
- 02Multiply by the conversion factor: 1 × 1000000 = 1.00000e+6 Bq.
Result1 MBq = 1.00000e+6 Bq

FAQ
What is the conversion factor from MBq to Bq?
1 MBq equals 1000000 Bq. To convert, multiply the value in megabecquerels by 1000000.
How do I convert 1 MBq to Bq?
1 MBq = 1.00000e+6 Bq. For any value, multiply by 1000000.
How do I convert Bq back to MBq?
Divide by the same factor — or equivalently, multiply by 1e-6. So 1 Bq = 1e-6 MBq.
When would I need to convert megabecquerel to becquerel?
Radioactivity (activity) conversions between MBq and Bq 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).
