Convert Milliroentgens to Microroentgens
Convert Milliroentgens (mR) to Microroentgens (µR) instantly and accurately.
Conversion Formula
µR = mR × 1000
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 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.
