About these units
The milliroentgen (mR) is a specialist or regional unit of radiation exposure, equal to 2.58e-7 coulombs per kilogram.
The microroentgen (µR) is a specialist or regional unit of radiation exposure, equal to 2.58e-10 coulombs per kilogram.
Going the other way, 1 microroentgen = 0.001 milliroentgens. Exposure measures the ionisation that X-rays or gamma rays produce in air. Survey meters and older equipment read in roentgen, R, while the SI unit is the coulomb per kilogram. Exactly 1 R is 2.58 × 10⁻⁴ C/kg. Exposure is not the same as absorbed or effective dose.
