dpstodpm

Convert disintegrations per second (dps) to disintegrations per minute (dpm).

Factor1 dps = 60 dpm

Converter

dps

Accepts numbers or expressions, e.g. 150 + 14.7

Result
60dpm

Rendered to 6 significant figures.

Formula

Formula
dpm = dps × 60

Multiply any value in disintegrations per second by 60 to obtain the value in disintegrations per minute.

Worked example

Convert 1 dps to dpm.

  1. 01Start with 1 dps.
  2. 02Multiply by the conversion factor: 1 × 60 = 60 dpm.
Result1 dps = 60 dpm

FAQ

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