Convert Microcuries to Rutherfords (µCi to Rd)
1 microcurie (µCi) = 0.037 rutherfords (Rd). 1 Rd = 27.02702703 µCi. Example: 15 µCi = 15 × 0.037 = 0.555 Rd.

How to Convert Microcurie to Rutherford
- 1 µCi = 0.037 Rd
- 1 Rd = 27.02702703 µCi
- Example: convert 15 µCi to Rd: 15 µCi = 15 × 0.037 Rd = 0.555 Rd
Formula
Rd = µCi × 0.037
or Rd = µCi ÷ 27.02702702703
Derivation from SI units:
- 1 µCi = 3.7 × 10⁴ Bq = 37 kBq.
- 1 Rd = 10⁶ Bq (obsolete).
- 1 µCi = 37000 Bq ÷ 1000000 Bq per Rd = 0.037 Rd
Both units are defined exactly, so the factor is exact. Microcurie definition: microcurie; Rutherford definition: rutherford.
Worked examples
- A reading of 2 µCi converts to 0.074 Rd.
2 µCi × 0.037 = 0.074 Rd - A value of 20 µCi is 0.74 Rd.
20 µCi × 0.037 = 0.74 Rd

Where it's used
Microcuries are used for check and calibration sources, while rutherfords appear in older nuclear physics literature. Both measure activity of a radioactive source, so the conversion is a fixed factor.
