Convert DPM to Kilobecquerels (dpm to kBq)
1 disintegration per minute (dpm) = 0.00001666666667 kilobecquerels (kBq). 1 kBq = 60000 dpm. Example: 15 dpm = 15 × 0.00001666666667 = 0.00025 kBq.

How to Convert DPM to Kilobecquerel
- 1 dpm = 0.00001666666667 kBq
- 1 kBq = 60000 dpm
- Example: convert 15 dpm to kBq: 15 dpm = 15 × 0.00001666666667 kBq = 0.00025 kBq
Formula
kBq = dpm × 0.00001666666666667
or kBq = dpm ÷ 60000
Derivation from SI units:
- 1 dpm = 1/60 Bq.
- 1 kBq = 10³ Bq.
- 1 dpm = 0.01666666666667 Bq ÷ 1000 Bq per kBq = 0.00001666666666667 kBq
Both units are defined exactly, so the factor is exact. DPM definition: disintegration per minute; Kilobecquerel definition: kilobecquerel.
Worked examples
- A reading of 600 dpm converts to 0.01 kBq.
600 dpm × 0.00001666666667 = 0.01 kBq - A value of 6000 dpm is 0.1 kBq.
6000 dpm × 0.00001666666667 = 0.1 kBq

Where it's used
DPM are used for wipe tests and contamination surveys, while kilobecquerels appear in laboratory sources and calibration standards. Both measure activity of a radioactive source, so the conversion is a fixed factor.

Frequently asked questions
How many kilobecquerels are in 1 disintegration per minute?
1 dpm = 0.00001666666667 kBq.
How do I convert disintegrations per minute to kilobecquerels?
Multiply the value in dpm by 0.00001666666667, or divide it by 60000. For example, 15 dpm × 0.00001666666667 = 0.00025 kBq.
Is the dpm to kBq 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).
