Result
1dps

Rendered to 6 significant figures.

Formula

Formula
dps = dpm × 0.01666667

Multiply any value in disintegrations per minute by 0.01666667 to obtain the value in disintegrations per second.

Worked example

Convert 60 dpm to dps.

  1. 01Start with 60 dpm.
  2. 02Multiply by the conversion factor: 60 × 0.01666667 = 1 dps.
Result60 dpm = 1 dps

FAQ

What is the conversion factor from dpm to dps?
1 dpm equals 0.01666667 dps. To convert, multiply the value in disintegrations per minute by 0.01666667.
How do I convert 1 dpm to dps?
1 dpm = 0.0166667 dps. For any value, multiply by 0.01666667.
How do I convert dps back to dpm?
Divide by the same factor — or equivalently, multiply by 60. So 1 dps = 60 dpm.
When would I need to convert disintegration per minute to disintegration per second?
Radioactivity (activity) conversions between dpm 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).
