How to Convert Milliohms to Microhms
To convert milliohms to microhms, multiply the electrical resistance by the following conversion ratio: 1,000 microhms/milliohm.
Since one milliohm is equal to 1,000 microhms, you can use this simple formula to convert:
The electrical resistance in microhms is equal to the electrical resistance in milliohms multiplied by 1,000.
For example, here's how to convert 5 milliohms to microhms using the formula above.
How Many Microhms Are in a Milliohm?
There are 1,000 microhms in a milliohm, which is why we use this value in the formula above.
Our milliohm to microhm calculator automatically converts your electrical resistance measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Milliohms and microhms are both units used to measure electrical resistance. Keep reading to learn more about each unit.
What Is a Milliohm?
A milliohm is a unit of electrical resistance equal to 1/1,000 of an ohm (0.001 Ω). One-thousandth of an Ohm. [1]
The milliohm is classified as a metric and SI-compatible unit of electrical resistance. Milliohms can be abbreviated as mΩ; for example, 1 milliohm can be written as 1 mΩ.
In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the milliohm (mΩ) a convenient decimal multiple of the ohm (Ω).
In practice, milliohms (mΩ) are widely used across fine-tolerance laboratory, analytical, and micro-scale electrical resistance measurements within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Microhm?
A microhm is a unit of electrical resistance equal to 1/1,000,000 of an ohm (0.000001 Ω). One-millionth of an Ohm. [2]
The microhm is classified as a metric and SI-compatible unit of electrical resistance. Microhms can be abbreviated as µΩ; for example, 1 microhm can be written as 1 µΩ.
In the metric system, "micro" is the standard SI prefix for millionths, or 10⁻⁶. This makes the microhm (µΩ) a convenient decimal multiple of the ohm (Ω).
In practice, microhms (µΩ) are widely used across fine-tolerance laboratory, analytical, and micro-scale electrical resistance measurements within SI metric workflows, engineering documentation, and technical data sheets.
When converting electrical resistance between milliohms (mΩ) and microhms (µΩ), keep full floating-point precision (1 mΩ = 1,000 µΩ; 1 µΩ = 0.001 mΩ) during intermediate calculations and round only the final microhm figure to match your instrument tolerance.
