Convert Microroentgens (µR) to Microcoulombs per kilogram (µC/kg) instantly and accurately.
Conversion Formula
µC/kg = µR × 0.000258
About Microroentgens
The microroentgen (µR) equals 2.58 × 10⁻¹⁰ C/kg. Standard unit for very low environmental gamma dose rates in legacy US instrumentation: airborne radiological surveys over background areas report µR/h; EPA environmental monitoring network stations historically logged µR/h for outdoor gamma levels. 1 µR = 2.58 × 10⁻¹⁰ C/kg.
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.
