Convert Nanocuries to Gigabecquerels (nCi to GBq)
1 nanocurie (nCi) = 3.7 × 10⁻⁸ gigabecquerels (GBq). 1 GBq = 27027027.03 nCi. Example: 15 nCi = 15 × 3.7 × 10⁻⁸ = 5.55 × 10⁻⁷ GBq.

How to Convert Nanocurie to Gigabecquerel
- 1 nCi = 3.7 × 10⁻⁸ GBq
- 1 GBq = 27027027.03 nCi
- Example: convert 15 nCi to GBq: 15 nCi = 15 × 3.7 × 10⁻⁸ GBq = 5.55 × 10⁻⁷ GBq
Formula
GBq = nCi × 3.7 × 10⁻⁸
or GBq = nCi ÷ 27027027.02703
Derivation from SI units:
- 1 nCi = 37 Bq.
- 1 GBq = 10⁹ Bq.
- 1 nCi = 37 Bq ÷ 1000000000 Bq per GBq = 3.7 × 10⁻⁸ GBq
Both units are defined exactly, so the factor is exact. Nanocurie definition: nanocurie; Gigabecquerel definition: gigabecquerel.
Worked examples
- A reading of 2 nCi converts to 7.4 × 10⁻⁸ GBq.
2 nCi × 3.7 × 10⁻⁸ = 7.4 × 10⁻⁸ GBq - A value of 20 nCi is 7.4 × 10⁻⁷ GBq.
20 nCi × 3.7 × 10⁻⁸ = 7.4 × 10⁻⁷ GBq
