Convert DPM to Nanocuries (dpm to nCi)
1 disintegration per minute (dpm) = 0.0004504504505 nanocuries (nCi). 1 nCi = 2220 dpm. Example: 15 dpm = 15 × 0.0004504504505 = 0.006756756757 nCi.

How to Convert DPM to Nanocurie
- 1 dpm = 0.0004504504505 nCi
- 1 nCi = 2220 dpm
- Example: convert 15 dpm to nCi: 15 dpm = 15 × 0.0004504504505 nCi = 0.006756756757 nCi
Formula
nCi = dpm ÷ 2220
Derivation from SI units:
- 1 dpm = 1/60 Bq.
- 1 nCi = 37 Bq.
- 1 dpm = 0.01666666666667 Bq ÷ 37 Bq per nCi = 0.0004504504504505 nCi
Both units are defined exactly, so the factor is exact. DPM definition: disintegration per minute; Nanocurie definition: nanocurie.
Worked examples
- A reading of 600 dpm converts to 0.2702702703 nCi.
600 dpm × 0.0004504504505 = 0.2702702703 nCi - A value of 6000 dpm is 2.702702703 nCi.
6000 dpm × 0.0004504504505 = 2.702702703 nCi

Where it's used
DPM are used for wipe tests and contamination surveys, while nanocuries appear in environmental sample activities. Both measure activity of a radioactive source, so the conversion is a fixed factor.

Frequently asked questions
How many nanocuries are in 1 disintegration per minute?
1 dpm = 0.0004504504505 nCi.
How do I convert disintegrations per minute to nanocuries?
Multiply the value in dpm by 0.0004504504505, or divide it by 2220. For example, 15 dpm × 0.0004504504505 = 0.006756756757 nCi.
Is the dpm to nCi 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).
