How to Convert Ampere-turns to Milliampere-turns
To convert ampere-turns to milliampere-turns, multiply the magnetomotive force by the following conversion ratio: 1,000 milliampere-turns/ampere-turn.
Since one ampere-turn is equal to 1,000 milliampere-turns, you can use this simple formula to convert:
The magnetomotive force in milliampere-turns is equal to the magnetomotive force in ampere-turns multiplied by 1,000.
For example, here's how to convert 10 ampere-turns to milliampere-turns using the formula above.
How Many Milliampere-turns Are in an Ampere-turn?
There are 1,000 milliampere-turns in an ampere-turn, which is why we use this value in the formula above.
Our ampere-turn to milliampere-turn calculator automatically converts your magnetomotive force measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Ampere-turns and milliampere-turns are both units used to measure magnetomotive force. Keep reading to learn more about each unit.
What Is an Ampere-turn?
SI unit of magnetomotive force (MMF). It serves as a primary reference unit for measuring magnetomotive force across scientific and practical applications. [1]
The ampere-turn is classified as an International System of Units (SI) unit of magnetomotive force. Ampere-turns can be abbreviated as At; for example, 1 ampere-turn can be written as 1 At.
As the primary coherent reference unit for magnetomotive force in this category, all other magnetomotive force units are mathematically anchored to the ampere-turn (At).
In practice, ampere-turns (At) are widely used across standard magnetomotive force applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
What Is a Milliampere-turn?
A milliampere-turn is a unit of magnetomotive force equal to 1/1,000 of an ampere-turn (0.001 At). Equal to 0.001 Ampere-turns. [2]
The milliampere-turn is classified as a metric and SI-compatible unit of magnetomotive force. Milliampere-turns can be abbreviated as mAt; for example, 1 milliampere-turn can be written as 1 mAt.
In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the milliampere-turn (mAt) a convenient decimal multiple of the ampere-turn (At).
In practice, milliampere-turns (mAt) are widely used across fine-tolerance laboratory, analytical, and micro-scale magnetomotive force measurements within SI metric workflows, engineering documentation, and technical data sheets.
When converting magnetomotive force between ampere-turns (At) and milliampere-turns (mAt), keep full floating-point precision (1 At = 1,000 mAt; 1 mAt = 0.001 At) during intermediate calculations and round only the final milliampere-turn figure to match your instrument tolerance.
