Factor1 dps = 0.001 kBq
Converter
dps
Accepts numbers or expressions, e.g. 150 + 14.7
Result
kBq
Rendered to 6 significant figures.
Formula
Formula
kBq = dps × 0.001
Multiply any value in disintegrations per second by 0.001 to obtain the value in kilobecquerels.
Worked example
Convert 1000 dps to kBq.
- 01Start with 1000 dps.
- 02Multiply by the conversion factor: 1000 × 0.001 = 1 kBq.
Result1000 dps = 1 kBq

FAQ
What is the conversion factor from dps to kBq?
1 dps equals 0.001 kBq. To convert, multiply the value in disintegrations per second by 0.001.
How do I convert 1 dps to kBq?
1 dps = 0.001 kBq. For any value, multiply by 0.001.
How do I convert kBq back to dps?
Divide by the same factor — or equivalently, multiply by 1000. So 1 kBq = 1000 dps.
When would I need to convert disintegration per second to kilobecquerel?
Radioactivity (activity) conversions between dps and kBq 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).
