Convert Millirems to Microrems
Convert Millirems (mrem) to Microrems (µrem) instantly and accurately.
Conversion Formula
µrem = mrem × 1000
About Millirems
The millirem (mrem) equals 10⁻³ rem = 10⁻⁵ Sv. Standard unit in US radiation protection: NRC occupational whole-body limit 5000 mrem/year; US average annual background ~300 mrem; EPA drinking-water dose limit 4 mrem/year; dose rates near US nuclear plant boundaries are reported in mrem/year. 1 mrem = 10⁻⁵ Sv = 10 µSv.
About Microrems
The microrem (µrem) equals 10⁻⁶ rem = 10⁻⁸ Sv. Used in legacy US health physics instrumentation and NRC licence documentation for extremely low ambient dose-rate measurements; older EPA environmental surveillance reports quote dose rates in µrem/h where modern instruments report nSv/h. 1 µrem = 10⁻⁸ Sv = 10⁻² µSv.
