Convert Rems to Microsieverts
Convert Rems (rem) to Microsieverts (µSv) instantly and accurately.
Conversion Formula
µSv = rem × 10000
About Rems
The rem (roentgen equivalent man) equals exactly 0.01 Sv = 1 cSv. The pre-SI unit of equivalent dose, still dominant in US regulation: NRC occupational whole-body limit 5 rem/year; 10 CFR Part 20 exposure limits cited in rem; US military personnel dose records maintained in rem. 1 rem = 0.01 Sv = 1 cSv.
About Microsieverts
The microsievert (µSv) equals 10⁻⁶ Sv. Standard unit for individual low-dose exposures: chest X-ray ~20 µSv effective dose; transatlantic flight ~80 µSv; dental panoramic X-ray ~10-25 µSv. Personal electronic dosimeters in medical and industrial workplaces accumulate and display dose in µSv. 1 µSv = 10⁻⁶ Sv.
