Convert Becquerels to Kilobecquerels (Bq to kBq)
1 becquerel (Bq) = 0.001 kilobecquerels (kBq). 1 kBq = 1000 Bq. Example: 15 Bq = 15 × 0.001 = 0.015 kBq.

How to Convert Becquerel to Kilobecquerel
- 1 Bq = 0.001 kBq
- 1 kBq = 1000 Bq
- Example: convert 15 Bq to kBq: 15 Bq = 15 × 0.001 kBq = 0.015 kBq
Formula
kBq = Bq ÷ 1000
Derivation from SI units:
- 1 Bq = 1 decay per second (s⁻¹).
- 1 kBq = 10³ Bq.
Both units are defined exactly, so the factor is exact. Becquerel definition: becquerel; Kilobecquerel definition: kilobecquerel.
Worked examples
- A reading of 100 Bq converts to 0.1 kBq.
100 Bq × 0.001 = 0.1 kBq - A value of 3700 Bq is 3.7 kBq.
3700 Bq × 0.001 = 3.7 kBq

Where it's used
Becquerels are used for food and environmental radioactivity limits, 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 becquerel?
1 Bq = 0.001 kBq.
How do I convert becquerels to kilobecquerels?
Multiply the value in Bq by 0.001, or divide it by 1000. For example, 15 Bq × 0.001 = 0.015 kBq.
Is the Bq to kBq conversion exact?
Yes. Both units are defined exactly, and 1 Bq is exactly 0.001 kBq.
