Convert Picocuries to Terabecquerels (pCi to TBq)
1 picocurie (pCi) = 3.7 × 10⁻¹⁴ terabecquerels (TBq). 1 TBq = 27027027030000 pCi. Example: 15 pCi = 15 × 3.7 × 10⁻¹⁴ = 5.55 × 10⁻¹³ TBq.

How to Convert Picocurie to Terabecquerel
- 1 pCi = 3.7 × 10⁻¹⁴ TBq
- 1 TBq = 27027027030000 pCi
- Example: convert 15 pCi to TBq: 15 pCi = 15 × 3.7 × 10⁻¹⁴ TBq = 5.55 × 10⁻¹³ TBq
Formula
TBq = pCi × 3.7 × 10⁻¹⁴
or TBq = pCi ÷ 27027027027030
Derivation from SI units:
- 1 pCi = 0.037 Bq.
- 1 TBq = 10¹² Bq.
- 1 pCi = 0.037 Bq ÷ 1000000000000 Bq per TBq = 3.7 × 10⁻¹⁴ TBq
Both units are defined exactly, so the factor is exact. Picocurie definition: picocurie; Terabecquerel definition: terabecquerel.
Worked examples
- A reading of 4 pCi converts to 1.48 × 10⁻¹³ TBq.
4 pCi × 3.7 × 10⁻¹⁴ = 1.48 × 10⁻¹³ TBq - A value of 20 pCi is 7.4 × 10⁻¹³ TBq.
20 pCi × 3.7 × 10⁻¹⁴ = 7.4 × 10⁻¹³ TBq
