Convert Becquerels to Nanocuries (Bq to nCi)
1 becquerel (Bq) = 0.02702702703 nanocuries (nCi). 1 nCi = 37 Bq. Example: 15 Bq = 15 × 0.02702702703 = 0.4054054054 nCi.

How to Convert Becquerel to Nanocurie
- 1 Bq = 0.02702702703 nCi
- 1 nCi = 37 Bq
- Example: convert 15 Bq to nCi: 15 Bq = 15 × 0.02702702703 nCi = 0.4054054054 nCi
Formula
nCi = Bq ÷ 37
Derivation from SI units:
- 1 Bq = 1 decay per second (s⁻¹).
- 1 nCi = 37 Bq.
Both units are defined exactly, so the factor is exact. Becquerel definition: becquerel; Nanocurie definition: nanocurie.
Worked examples
- A reading of 100 Bq converts to 2.702702703 nCi.
100 Bq × 0.02702702703 = 2.702702703 nCi - A value of 3700 Bq is 100 nCi.
3700 Bq × 0.02702702703 = 100 nCi

Frequently asked questions
How many nanocuries are in 1 becquerel?
1 Bq = 0.02702702703 nCi.
How do I convert becquerels to nanocuries?
Multiply the value in Bq by 0.02702702703, or divide it by 37. For example, 15 Bq × 0.02702702703 = 0.4054054054 nCi.
Is the Bq to nCi 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).
