Convert Nanocuries to Rutherfords (nCi to Rd)
1 nanocurie (nCi) = 0.000037 rutherfords (Rd). 1 Rd = 27027.02703 nCi. Example: 15 nCi = 15 × 0.000037 = 0.000555 Rd.

How to Convert Nanocurie to Rutherford
- 1 nCi = 0.000037 Rd
- 1 Rd = 27027.02703 nCi
- Example: convert 15 nCi to Rd: 15 nCi = 15 × 0.000037 Rd = 0.000555 Rd
Formula
Rd = nCi × 0.000037
or Rd = nCi ÷ 27027.02702703
Derivation from SI units:
- 1 nCi = 37 Bq.
- 1 Rd = 10⁶ Bq (obsolete).
- 1 nCi = 37 Bq ÷ 1000000 Bq per Rd = 0.000037 Rd
Both units are defined exactly, so the factor is exact. Nanocurie definition: nanocurie; Rutherford definition: rutherford.
Worked examples
- A reading of 2 nCi converts to 0.000074 Rd.
2 nCi × 0.000037 = 0.000074 Rd - A value of 20 nCi is 0.00074 Rd.
20 nCi × 0.000037 = 0.00074 Rd
