Convert Picocuries to Gigabecquerels (pCi to GBq)
1 picocurie (pCi) = 3.7 × 10⁻¹¹ gigabecquerels (GBq). 1 GBq = 27027027030 pCi. Example: 15 pCi = 15 × 3.7 × 10⁻¹¹ = 5.55 × 10⁻¹⁰ GBq.

How to Convert Picocurie to Gigabecquerel
- 1 pCi = 3.7 × 10⁻¹¹ GBq
- 1 GBq = 27027027030 pCi
- Example: convert 15 pCi to GBq: 15 pCi = 15 × 3.7 × 10⁻¹¹ GBq = 5.55 × 10⁻¹⁰ GBq
Formula
GBq = pCi × 3.7 × 10⁻¹¹
or GBq = pCi ÷ 27027027027.03
Derivation from SI units:
- 1 pCi = 0.037 Bq.
- 1 GBq = 10⁹ Bq.
- 1 pCi = 0.037 Bq ÷ 1000000000 Bq per GBq = 3.7 × 10⁻¹¹ GBq
Both units are defined exactly, so the factor is exact. Picocurie definition: picocurie; Gigabecquerel definition: gigabecquerel.
Worked examples
- A reading of 4 pCi converts to 1.48 × 10⁻¹⁰ GBq.
4 pCi × 3.7 × 10⁻¹¹ = 1.48 × 10⁻¹⁰ GBq - A value of 20 pCi is 7.4 × 10⁻¹⁰ GBq.
20 pCi × 3.7 × 10⁻¹¹ = 7.4 × 10⁻¹⁰ GBq
