Formula
GBq = PBq × 1000000
Multiply any value in petabecquerels by 1000000 to obtain the value in gigabecquerels.
Worked example
Convert 1 PBq to GBq.
- 01Start with 1 PBq.
- 02Multiply by the conversion factor: 1 × 1000000 = 1.00000e+6 GBq.
Result1 PBq = 1.00000e+6 GBq

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