How to Convert Rutherford to Nanocurie
- 1 Rd = 27027.02703 nCi
- 1 nCi = 0.000037 Rd
- Example: convert 15 Rd to nCi: 15 Rd = 15 × 27027.02703 nCi = 405405.4054 nCi
Formula
nCi = Rd × 27027.02702703
Derivation from SI units:
- 1 Rd = 10⁶ Bq (obsolete).
- 1 nCi = 37 Bq.
- 1 Rd = 1000000 Bq ÷ 37 Bq per nCi = 27027.02702703 nCi
Both units are defined exactly, so the factor is exact. Rutherford definition: rutherford; Nanocurie definition: nanocurie.
Worked examples
- A reading of 2 Rd converts to 54054.05405 nCi.
2 Rd × 27027.02703 = 54054.05405 nCi - A value of 20 Rd is 540540.5405 nCi.
20 Rd × 27027.02703 = 540540.5405 nCi
