Convert Microrems to Sieverts
Convert Microrems (µrem) to Sieverts (Sv) instantly and accurately.
Conversion Formula
Sv = µrem × 1.000000000e-8
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.
About Sieverts
The sievert (Sv) is the SI coherent unit of equivalent and effective dose, equal to 1 J/kg of absorbed dose weighted by radiation type. Named after Rolf Sievert (Swedish radiophysicist, 1896-1966). Whole-body LD50 for acute exposure ~3-5 Sv; ICRP emergency responder limit 0.25 Sv; acute radiation syndrome threshold ~1 Sv. 1 Sv = 100 rem = 1 J/kg.
