Convert Kilobecquerels to Curies (kBq to Ci)
1 kilobecquerel (kBq) = 2.702702703 × 10⁻⁸ curies (Ci). 1 Ci = 37000000 kBq. Example: 15 kBq = 15 × 2.702702703 × 10⁻⁸ = 4.054054054 × 10⁻⁷ Ci.

How to Convert Kilobecquerel to Curie
- 1 kBq = 2.702702703 × 10⁻⁸ Ci
- 1 Ci = 37000000 kBq
- Example: convert 15 kBq to Ci: 15 kBq = 15 × 2.702702703 × 10⁻⁸ Ci = 4.054054054 × 10⁻⁷ Ci
Formula
Ci = kBq ÷ 37000000
Derivation from SI units:
- 1 kBq = 10³ Bq.
- 1 Ci = 3.7 × 10¹⁰ Bq exactly (originally the activity of 1 g of radium-226).
- 1 kBq = 1000 Bq ÷ 37000000000 Bq per Ci = 2.702702702703 × 10⁻⁸ Ci
Both units are defined exactly, so the factor is exact. Kilobecquerel definition: kilobecquerel; Curie definition: curie.
Worked examples
- A reading of 2 kBq converts to 5.405405405 × 10⁻⁸ Ci.
2 kBq × 2.702702703 × 10⁻⁸ = 5.405405405 × 10⁻⁸ Ci - A value of 20 kBq is 5.405405405 × 10⁻⁷ Ci.
20 kBq × 2.702702703 × 10⁻⁸ = 5.405405405 × 10⁻⁷ Ci

Frequently asked questions
How many curies are in 1 kilobecquerel?
1 kBq = 2.702702703 × 10⁻⁸ Ci.
How do I convert kilobecquerels to curies?
Multiply the value in kBq by 2.702702703 × 10⁻⁸, or divide it by 37000000. For example, 15 kBq × 2.702702703 × 10⁻⁸ = 4.054054054 × 10⁻⁷ Ci.
Is the kBq to Ci 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).
