Formula
Formula
MBq = Bq × 1e-6
Multiply any value in becquerels by 1e-6 to obtain the value in megabecquerels.
Worked example
Convert 1e+7 Bq to MBq.
- 01Start with 1e+7 Bq.
- 02Multiply by the conversion factor: 1e+7 × 1e-6 = 10 MBq.
Result1e+7 Bq = 10 MBq

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