Milliroentgens (mR)
Kilocoulombs per kilogram (kC/kg)

Conversion Formula

kC/kg = mR × 2.580000000e-10

About Milliroentgens

The milliroentgen (mR) equals 2.58 × 10⁻⁷ C/kg. Standard unit in US health physics for area gamma surveys: personal dosimeters and Geiger counters in medical and industrial radiography settings display mR/h; NRC licence conditions often specify dose-rate limits in mR/h at facility boundaries. 1 mR = 2.58 × 10⁻⁷ C/kg.

About Kilocoulombs per kilogram

The kilocoulomb per kilogram (kC/kg) equals 10³ C/kg ≈ 3.88 × 10⁶ R. Encountered only in extreme prompt-radiation environments such as nuclear weapon burst regions and high-power flash X-ray facility calibration; at this exposure level all air volumes are multiply ionised and conventional dosimetry models break down. 1 kC/kg = 10³ C/kg.
