Convert Picocuries to Nanocuries (pCi to nCi)
1 picocurie (pCi) = 0.001 nanocuries (nCi). 1 nCi = 1000 pCi. Example: 15 pCi = 15 × 0.001 = 0.015 nCi.

How to Convert Picocurie to Nanocurie
- 1 pCi = 0.001 nCi
- 1 nCi = 1000 pCi
- Example: convert 15 pCi to nCi: 15 pCi = 15 × 0.001 nCi = 0.015 nCi
Formula
nCi = pCi ÷ 1000
Derivation from SI units:
- 1 pCi = 0.037 Bq.
- 1 nCi = 37 Bq.
- 1 pCi = 0.037 Bq ÷ 37 Bq per nCi = 0.001 nCi
Both units are defined exactly, so the factor is exact. Picocurie definition: picocurie; Nanocurie definition: nanocurie.
Worked examples
- A reading of 4 pCi converts to 0.004 nCi.
4 pCi × 0.001 = 0.004 nCi - A value of 20 pCi is 0.02 nCi.
20 pCi × 0.001 = 0.02 nCi

Frequently asked questions
How many nanocuries are in 1 picocurie?
1 pCi = 0.001 nCi.
How do I convert picocuries to nanocuries?
Multiply the value in pCi by 0.001, or divide it by 1000. For example, 15 pCi × 0.001 = 0.015 nCi.
Is the pCi to nCi conversion exact?
Yes. Both units are defined exactly, and 1 pCi is exactly 0.001 nCi.
