Formula
Formula
MBq = pCi × 3.7e-8
Multiply any value in picocuries by 3.7e-8 to obtain the value in megabecquerels.
Worked example
Convert 1e+8 pCi to MBq.
- 01Start with 1e+8 pCi.
- 02Multiply by the conversion factor: 1e+8 × 3.7e-8 = 3.7 MBq.
Result1e+8 pCi = 3.7 MBq

FAQ
What is the conversion factor from pCi to MBq?
1 pCi equals 3.7e-8 MBq. To convert, multiply the value in picocuries by 3.7e-8.
How do I convert 1 pCi to MBq?
1 pCi = 3.7e-8 MBq. For any value, multiply by 3.7e-8.
How do I convert MBq back to pCi?
Divide by the same factor — or equivalently, multiply by 2.702703e+7. So 1 MBq = 2.7027e+7 pCi.
When would I need to convert picocurie to megabecquerel?
Radioactivity (activity) conversions between pCi 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).
