Vice Versa: coulomb per kilogram to roentgen

Roentgen

The roentgen is the traditional CGS unit of radiation exposure, defined as the amount of X-ray or gamma radiation that produces 2.58×10⁻⁴ coulombs of charge per kilogram of air. 


Coulomb per Kilogram

The coulomb per kilogram is the SI unit of radiation exposure, measuring the amount of electric charge produced by ionizing radiation per unit mass of air. It replaced the roentgen in the SI system.
