Convert Megaroentgens to Microroentgens
Convert Megaroentgens (MR) to Microroentgens (µR) instantly and accurately.
Conversion Formula
µR = MR × 1000000000000
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.
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.
