Convert Microcuries to Nanocuries (µCi to nCi)
1 microcurie (µCi) = 1000 nanocuries (nCi). 1 nCi = 0.001 µCi. Example: 15 µCi = 15 × 1000 = 15000 nCi.

How to Convert Microcurie to Nanocurie
- 1 µCi = 1000 nCi
- 1 nCi = 0.001 µCi
- Example: convert 15 µCi to nCi: 15 µCi = 15 × 1000 nCi = 15000 nCi
Formula
nCi = µCi × 1000
Derivation from SI units:
- 1 µCi = 3.7 × 10⁴ Bq = 37 kBq.
- 1 nCi = 37 Bq.
- 1 µCi = 37000 Bq ÷ 37 Bq per nCi = 1000 nCi
Both units are defined exactly, so the factor is exact. Microcurie definition: microcurie; Nanocurie definition: nanocurie.
Worked examples
- A reading of 2 µCi converts to 2000 nCi.
2 µCi × 1000 = 2000 nCi - A value of 20 µCi is 20000 nCi.
20 µCi × 1000 = 20000 nCi
