How to Convert Millisieverts to Millirem
To convert millisieverts to millirem, multiply the radiation dose by the following conversion ratio: 100 millirem/millisievert.
Since one millisievert is equal to 100 millirem, you can use this simple formula to convert:
The radiation dose in millirem is equal to the radiation dose in millisieverts multiplied by 100.
For example, here's how to convert 5 millisieverts to millirem using the formula above.
How Many Millirem Are in a Millisievert?
There are 100 millirem in a millisievert, which is why we use this value in the formula above.
Our millisievert to millirem calculator automatically converts your radiation dose measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Millisieverts and millirem are both units used to measure radiation dose. Keep reading to learn more about each unit.
What Is a Millisievert?
A millisievert is a unit of radiation dose equal to 1/1,000 of a sievert (0.001 Sv). Medical imaging & dosimetry unit (1 mSv = 0.001 Sv = 100 mrem). [1]
The millisievert is classified as a metric and SI-compatible unit of radiation dose. Millisieverts can be abbreviated as mSv; for example, 1 millisievert can be written as 1 mSv.
In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the millisievert (mSv) a convenient decimal multiple of the sievert (Sv).
In practice, millisieverts (mSv) 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 millisieverts (mSv) and millirem (mrem), keep full floating-point precision (1 mSv = 100 mrem; 1 mrem = 0.01 mSv) during intermediate calculations and round only the final millirem figure to match your instrument tolerance.
