Convert DPM to Picocuries (dpm to pCi)
1 disintegration per minute (dpm) = 0.4504504505 picocuries (pCi). 1 pCi = 2.22 dpm. Example: 15 dpm = 15 × 0.4504504505 = 6.756756757 pCi.

How to Convert DPM to Picocurie
- 1 dpm = 0.4504504505 pCi
- 1 pCi = 2.22 dpm
- Example: convert 15 dpm to pCi: 15 dpm = 15 × 0.4504504505 pCi = 6.756756757 pCi
Formula
pCi = dpm × 0.4504504504505
or pCi = dpm ÷ 2.22
Derivation from SI units:
- 1 dpm = 1/60 Bq.
- 1 pCi = 0.037 Bq.
- 1 dpm = 0.01666666666667 Bq ÷ 0.037 Bq per pCi = 0.4504504504505 pCi
Both units are defined exactly, so the factor is exact. DPM definition: disintegration per minute; Picocurie definition: picocurie.
Worked examples
- A reading of 600 dpm converts to 270.2702703 pCi.
600 dpm × 0.4504504505 = 270.2702703 pCi - A value of 6000 dpm is 2702.702703 pCi.
6000 dpm × 0.4504504505 = 2702.702703 pCi

Where it's used
DPM are used for wipe tests and contamination surveys, while picocuries appear in radon in homes (pCi/L). Both measure activity of a radioactive source, so the conversion is a fixed factor.

Frequently asked questions
How many picocuries are in 1 disintegration per minute?
1 dpm = 0.4504504505 pCi.
How do I convert disintegrations per minute to picocuries?
Multiply the value in dpm by 0.4504504505, or divide it by 2.22. For example, 15 dpm × 0.4504504505 = 6.756756757 pCi.
Is the dpm to pCi conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
