How to Convert Rutherfords to Curies
The rutherford and curie are both units of radioactivity. By definition, 1 curie equals exactly 37000 rutherfords. This means to convert rutherfords to curies, you divide by 37000.
Formula
Step-by-Step Example
Convert 5 Rd to curies:
We need to convert rutherfords to curies
Since 1 Ci = 37000 Rd, divide by 37000
5 ÷ 37000 = 0.0001351351
5 Rd = 0.0001351351 Ci

About These Units
Rutherford (Rd)
The rutherford (Rd) equals exactly 10⁶ decays per second or 1 MBq. Named after Ernest Rutherford, father of nuclear physics. Proposed as an SI-compatible unit but the becquerel was adopted instead. One rutherford = 27 microcuries.
Curie (Ci)
The curie (Ci) is the traditional unit of radioactivity, originally defined as the activity of 1 gram of Ra-226. One curie = 3.7×10¹⁰ decays/second = 37 GBq exactly. Named after Marie and Pierre Curie. Still used in US nuclear medicine and industry.
