Convert Nanocuries to DPM (nCi to dpm)
1 nanocurie (nCi) = 2220 disintegrations per minute (dpm). 1 dpm = 0.0004504504505 nCi. Example: 15 nCi = 15 × 2220 = 33300 dpm.

How to Convert Nanocurie to DPM
- 1 nCi = 2220 dpm
- 1 dpm = 0.0004504504505 nCi
- Example: convert 15 nCi to dpm: 15 nCi = 15 × 2220 dpm = 33300 dpm
Formula
dpm = nCi × 2220
Derivation from SI units:
- 1 nCi = 37 Bq.
- 1 dpm = 1/60 Bq.
- 1 nCi = 37 Bq ÷ 0.01666666666667 Bq per dpm = 2220 dpm
Both units are defined exactly, so the factor is exact. Nanocurie definition: nanocurie; DPM definition: disintegration per minute.
Worked examples
- A reading of 2 nCi converts to 4440 dpm.
2 nCi × 2220 = 4440 dpm - A value of 20 nCi is 44400 dpm.
20 nCi × 2220 = 44400 dpm
