MR = µC/kg × 3.875968992e-9
About Microcoulombs per kilogram
The microcoulomb per kilogram (µC/kg) equals 10⁻⁶ C/kg ≈ 3.88 mR. Used in precision ionisation chamber measurements for X-ray beam quality characterisation; national standards laboratories express free-air chamber calibration factors in µC/kg. 1 µC/kg = 10⁻⁶ C/kg = 10⁻³ mC/kg.
About Megaroentgens
The megaroentgen (MR) equals 258 C/kg. Used only in extreme radiation environments - nuclear detonation effects calculations, prompt gamma pulse environments, and legacy radiation hardness assurance for military electronics specify total ionising exposure in MR(air); calibrated flash X-ray simulators output pulse exposures in MR. 1 MR = 258 C/kg = 10⁶ R.
