FAQ
What is the conversion factor from TBq to GBq?
1 TBq equals 1000 GBq. To convert, multiply the value in terabecquerels by 1000.
How do I convert 1 TBq to GBq?
1 TBq = 1000 GBq. For any value, multiply by 1000.
How do I convert GBq back to TBq?
Divide by the same factor — or equivalently, multiply by 0.001. So 1 GBq = 0.001 TBq.
When would I need to convert terabecquerel to gigabecquerel?
Radioactivity (activity) conversions between TBq 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).
