FAQ
What is the conversion factor from kBq to dpm?
1 kBq equals 60000 dpm. To convert, multiply the value in kilobecquerels by 60000.
How do I convert 1 kBq to dpm?
1 kBq = 60000 dpm. For any value, multiply by 60000.
How do I convert dpm back to kBq?
Divide by the same factor — or equivalently, multiply by 1.666667e-5. So 1 dpm = 1.66667e-5 kBq.
When would I need to convert kilobecquerel to disintegration per minute?
Radioactivity (activity) conversions between kBq and dpm 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).
