Convert Kilobecquerels to Microcuries (kBq to µCi)
1 kilobecquerel (kBq) = 0.02702702703 microcuries (µCi). 1 µCi = 37 kBq. Example: 15 kBq = 15 × 0.02702702703 = 0.4054054054 µCi.

How to Convert Kilobecquerel to Microcurie
- 1 kBq = 0.02702702703 µCi
- 1 µCi = 37 kBq
- Example: convert 15 kBq to µCi: 15 kBq = 15 × 0.02702702703 µCi = 0.4054054054 µCi
Formula
µCi = kBq ÷ 37
Derivation from SI units:
- 1 kBq = 10³ Bq.
- 1 µCi = 3.7 × 10⁴ Bq = 37 kBq.
- 1 kBq = 1000 Bq ÷ 37000 Bq per µCi = 0.02702702702703 µCi
Both units are defined exactly, so the factor is exact. Kilobecquerel definition: kilobecquerel; Microcurie definition: microcurie.
Worked examples
- A reading of 2 kBq converts to 0.05405405405 µCi.
2 kBq × 0.02702702703 = 0.05405405405 µCi - A value of 20 kBq is 0.5405405405 µCi.
20 kBq × 0.02702702703 = 0.5405405405 µCi

Frequently asked questions
How many microcuries are in 1 kilobecquerel?
1 kBq = 0.02702702703 µCi.
How do I convert kilobecquerels to microcuries?
Multiply the value in kBq by 0.02702702703, or divide it by 37. For example, 15 kBq × 0.02702702703 = 0.4054054054 µCi.
Is the kBq to µCi 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).
