How to Convert Ohms to Microhms
To convert ohms to microhms, multiply the electrical resistance by the following conversion ratio: 1,000,000 microhms/ohm.
Since one ohm is equal to 1,000,000 microhms, you can use this simple formula to convert:
The electrical resistance in microhms is equal to the electrical resistance in ohms multiplied by 1,000,000.
For example, here's how to convert 5 ohms to microhms using the formula above.
How Many Microhms Are in an Ohm?
There are 1,000,000 microhms in an ohm, which is why we use this value in the formula above.
Our ohm to microhm calculator automatically converts your electrical resistance measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Ohms and microhms are both units used to measure electrical resistance. Keep reading to learn more about each unit.
What Is an Ohm?
SI unit of electrical resistance (1 V/A). It serves as a primary reference unit for measuring electrical resistance across scientific and practical applications. [1]
The ohm is classified as an International System of Units (SI) unit of electrical resistance. Ohms can be abbreviated as Ω; for example, 1 ohm can be written as 1 Ω.
As the primary coherent reference unit for electrical resistance in this category, all other electrical resistance units are mathematically anchored to the ohm (Ω).
In practice, ohms (Ω) are widely used across standard electrical resistance applications within International System of Units (SI) 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 ohms (Ω) and microhms (µΩ), keep full floating-point precision (1 Ω = 1,000,000 µΩ; 1 µΩ = 0.000001 Ω) during intermediate calculations and round only the final microhm figure to match your instrument tolerance.
