Sievert to Rem Conversion

Dose equivalent radiation uses different measurement units worldwide. Here are some simple conversions of these units.

millisievert (1 mSv = 10⁻³Sv = 0.001 Sv)

microsievert (1 μSv = 10⁻⁶Sv = 0.000001 Sv).

Equivalent dose is measured in the United States is in rem

1 rem = 0.01 Sv = 10 mSv
1 mrem = 0.00001 Sv = 0.01 mSv = 10 μSv
1 Sv = 100 rem = 100,000 mrem (or millirem)
1 mSv = 100 mrem = 0.1 rem
1 μSv = 0.1 mrem

The rem and millirem (abbreviated mrem), as with other customary units in the United States, are in wider use among the nuclear power industry, general public, and the government. However, SI units such as the sievert are frequently encountered in academic, scientific, and engineering environments.
