About Roentgen and Coulombs per Kilogram

Roentgen (R) is a legacy unit of radiation exposure, defined as the amount of X or gamma radiation required to produce one electrostatic unit of charge in one cubic centimeter of dry air.

Coulomb per kilogram (C/kg) is the SI unit of radiation exposure, representing the amount of ionizing radiation that produces a given amount of electric charge in a kilogram of air.

Conversion factor:

1 R = 0.000258 C/kg
1 C/kg ≈ 3875.97 R
