How to Convert Microsieverts to Millirem
To convert microsieverts to millirem, multiply the radiation dose by the following conversion ratio: 0.1 millirem/microsievert.
Since one microsievert is equal to 0.1 millirem, you can use this simple formula to convert:
The radiation dose in millirem is equal to the radiation dose in microsieverts multiplied by 0.1.
For example, here's how to convert 5 microsieverts to millirem using the formula above.
How Many Millirem Are in a Microsievert?
There are 0.1 millirem in a microsievert, which is why we use this value in the formula above.
Our microsievert to millirem calculator automatically converts your radiation dose measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Microsieverts and millirem are both units used to measure radiation dose. Keep reading to learn more about each unit.
What Is a Microsievert?
A microsievert is a unit of radiation dose equal to 1/1,000,000 of a sievert (0.000001 Sv). Background radiation dosimetry unit (10⁻⁶ Sv = 0.1 mrem). [1]
The microsievert is classified as a metric and SI-compatible unit of radiation dose. Microsieverts can be abbreviated as µSv; for example, 1 microsievert can be written as 1 µSv.
In the metric system, "micro" is the standard SI prefix for millionths, or 10⁻⁶. This makes the microsievert (µSv) a convenient decimal multiple of the sievert (Sv).
In practice, microsieverts (µSv) are widely used across fine-tolerance laboratory, analytical, and micro-scale radiation dose measurements within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Millirem?
A millirem is a unit of radiation dose equal to 1/100,000 of a sievert (0.00001 Sv). US occupational dosimetry unit (1 mrem = 10 µSv = 0.01 mSv). [2]
The millirem is classified as a standard unit of radiation dose. Millirem can be abbreviated as mrem; for example, 1 millirem can be written as 1 mrem.
In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the millirem (mrem) a convenient decimal multiple of the sievert (Sv).
In practice, millirem (mrem) are widely used across fine-tolerance laboratory, analytical, and micro-scale radiation dose measurements within international standard workflows, engineering documentation, and technical data sheets.
When converting radiation dose between microsieverts (µSv) and millirem (mrem), keep full floating-point precision (1 µSv = 0.1 mrem; 1 mrem = 10 µSv) during intermediate calculations and round only the final millirem figure to match your instrument tolerance.
