How to Convert Millicuries to Rutherfords
The millicurie and rutherford are both units of radioactivity. By definition, 1 millicurie equals exactly 37000000000 rutherfords. This means to convert millicuries to rutherfords, you multiply by 37000000000.
Formula
Step-by-Step Example
Convert 5 mCi to rutherfords:
We need to convert millicuries to rutherfords
Since 1 mCi = 37000000000 Rd, multiply by 37000000000
5 × 37000000000 = 185000000000
5 mCi = 185000000000 Rd

About These Units
Millicurie (mCi)
A millicurie (mCi) equals 0.001 curie or 37 MBq. Standard unit for nuclear medicine imaging in US: thyroid uptake 0.1-0.2 mCi, bone scan 20-30 mCi, cardiac stress test 25-35 mCi. Laboratory calibration sources: 1-10 mCi typical.
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.
