About converting Roentgen to Coulomb/kilogram

Roentgen is the source measurement selected for this radiation-exposure conversion. This conversion involves units that describe the ionization produced by radiation in air. These units may appear in historical records, calibration data, and radiation-protection references. Coulomb/kilogram is the target measurement selected for this radiation-exposure conversion. For this direction, one Roentgen is equal to 0.000258 Coulomb/kilogram.

Roentgen to Coulomb/kilogram formula

To convert from Roentgen to Coulomb/kilogram, multiply the starting value by 0.000258. This factor expresses how one Roentgen relates to the selected Coulomb/kilogram unit.
