How to Convert Sieverts to Microsieverts
To convert sieverts to microsieverts, multiply the radiation dose by the following conversion ratio: 1,000,000 microsieverts/sievert.
Since one sievert is equal to 1,000,000 microsieverts, you can use this simple formula to convert:
The radiation dose in microsieverts is equal to the radiation dose in sieverts multiplied by 1,000,000.
For example, here's how to convert 10 sieverts to microsieverts using the formula above.
How Many Microsieverts Are in a Sievert?
There are 1,000,000 microsieverts in a sievert, which is why we use this value in the formula above.
Our sievert to microsievert calculator automatically converts your radiation dose measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Sieverts and microsieverts are both units used to measure radiation dose. Keep reading to learn more about each unit.
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. [1]
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.
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). [2]
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.
When converting radiation dose between sieverts (Sv) and microsieverts (µSv), keep full floating-point precision (1 Sv = 1,000,000 µSv; 1 µSv = 0.000001 Sv) during intermediate calculations and round only the final microsievert figure to match your instrument tolerance.
