Formula
Formula
dps = pCi × 0.037
Multiply any value in picocuries by 0.037 to obtain the value in disintegrations per second.
Worked example
Convert 100 pCi to dps.
- 01Start with 100 pCi.
- 02Multiply by the conversion factor: 100 × 0.037 = 3.7 dps.
Result100 pCi = 3.7 dps

FAQ
What is the conversion factor from pCi to dps?
1 pCi equals 0.037 dps. To convert, multiply the value in picocuries by 0.037.
How do I convert 1 pCi to dps?
1 pCi = 0.037 dps. For any value, multiply by 0.037.
How do I convert dps back to pCi?
Divide by the same factor — or equivalently, multiply by 27.02703. So 1 dps = 27.027 pCi.
When would I need to convert picocurie to disintegration per second?
Radioactivity (activity) conversions between pCi and dps 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).
