How to Convert Microhms to Milliohms
To convert microhms to milliohms, multiply the electrical resistance by the following conversion ratio: 0.001 milliohms/microhm.
Since one microhm is equal to 0.001 milliohms, you can use this simple formula to convert:
The electrical resistance in milliohms is equal to the electrical resistance in microhms multiplied by 0.001.
For example, here's how to convert 5 microhms to milliohms using the formula above.
How Many Milliohms Are in a Microhm?
There are 0.001 milliohms in a microhm, which is why we use this value in the formula above.
Our microhm to milliohm calculator automatically converts your electrical resistance measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Microhms and milliohms are both units used to measure electrical resistance. Keep reading to learn more about each unit.
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. [1]
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.
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. [2]
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.
When converting electrical resistance between microhms (µΩ) and milliohms (mΩ), keep full floating-point precision (1 µΩ = 0.001 mΩ; 1 mΩ = 1,000 µΩ) during intermediate calculations and round only the final milliohm figure to match your instrument tolerance.
