How to Convert Milliteslas to Teslas
To convert milliteslas to teslas, multiply the magnetic flux density by the following conversion ratio: 0.001 teslas/millitesla.
Since one millitesla is equal to 0.001 teslas, you can use this simple formula to convert:
The magnetic flux density in teslas is equal to the magnetic flux density in milliteslas multiplied by 0.001.
For example, here's how to convert 5 milliteslas to teslas using the formula above.
How Many Teslas Are in a Millitesla?
There are 0.001 teslas in a millitesla, which is why we use this value in the formula above.
Our millitesla to tesla calculator automatically converts your magnetic flux density measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Milliteslas and teslas are both units used to measure magnetic flux density. Keep reading to learn more about each unit.
What Is a Millitesla?
A millitesla is a unit of magnetic flux density equal to 1/1,000 of a tesla (0.001 T). One-thousandth of a Tesla (10 Gauss). [1]
The millitesla is classified as a metric and SI-compatible unit of magnetic flux density. Milliteslas can be abbreviated as mT; for example, 1 millitesla can be written as 1 mT.
In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the millitesla (mT) a convenient decimal multiple of the tesla (T).
In practice, milliteslas (mT) are widely used across fine-tolerance laboratory, analytical, and micro-scale magnetic flux density measurements within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Tesla?
SI unit of magnetic flux density (1 Wb/m² = 10,000 Gauss). It serves as a primary reference unit for measuring magnetic flux density across scientific and practical applications. [2]
The tesla is classified as an International System of Units (SI) unit of magnetic flux density. Teslas can be abbreviated as T; for example, 1 tesla can be written as 1 T.
As the primary coherent reference unit for magnetic flux density in this category, all other magnetic flux density units are mathematically anchored to the tesla (T).
In practice, teslas (T) are widely used across standard magnetic flux density applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
When converting magnetic flux density between milliteslas (mT) and teslas (T), keep full floating-point precision (1 mT = 0.001 T; 1 T = 1,000 mT) during intermediate calculations and round only the final tesla figure to match your instrument tolerance.
