How to Convert Microsieverts to Sieverts
To convert microsieverts to sieverts, multiply the radiation dose by the following conversion ratio: 0.000001 sieverts/microsievert.
Since one microsievert is equal to 0.000001 sieverts, you can use this simple formula to convert:
The radiation dose in sieverts is equal to the radiation dose in microsieverts multiplied by 0.000001.
For example, here's how to convert 10 microsieverts to sieverts using the formula above.
How Many Sieverts Are in a Microsievert?
There are 0.000001 sieverts in a microsievert, which is why we use this value in the formula above.
Our microsievert to sievert calculator automatically converts your radiation dose measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Microsieverts and sieverts 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 Sievert?
SI derived unit of ionizing radiation equivalent dose (1 Sv = 100 rem). It serves as a primary reference unit for measuring radiation dose across scientific and practical applications. [2]
The sievert is classified as an International System of Units (SI) unit of radiation dose. Sieverts can be abbreviated as Sv; for example, 1 sievert can be written as 1 Sv.
As the primary coherent reference unit for radiation dose in this category, all other radiation dose units are mathematically anchored to the sievert (Sv).
In practice, sieverts (Sv) are widely used across standard radiation dose applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
When converting radiation dose between microsieverts (µSv) and sieverts (Sv), keep full floating-point precision (1 µSv = 0.000001 Sv; 1 Sv = 1,000,000 µSv) during intermediate calculations and round only the final sievert figure to match your instrument tolerance.
