How to Convert Megohms to Microhms
To convert megohms to microhms, multiply the electrical resistance by the following conversion ratio: 1e+12 microhms/megohm.
Since one megohm is equal to 1e+12 microhms, you can use this simple formula to convert:
The electrical resistance in microhms is equal to the electrical resistance in megohms multiplied by 1e+12.
For example, here's how to convert 5 megohms to microhms using the formula above.
How Many Microhms Are in a Megohm?
There are 1e+12 microhms in a megohm, which is why we use this value in the formula above.
Our megohm to microhm calculator automatically converts your electrical resistance measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Megohms and microhms are both units used to measure electrical resistance. Keep reading to learn more about each unit.
What Is a Megohm?
A megohm is a unit of electrical resistance equal to 1,000,000 ohms (Ω), the base unit for electrical resistance. Equal to 1,000,000 Ohms (1,000 kΩ). [1]
The megohm is classified as an International System of Units (SI) unit of electrical resistance. Megohms can be abbreviated as MΩ; for example, 1 megohm can be written as 1 MΩ.
When working with megohms (MΩ) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, megohms (MΩ) are widely used across large-scale industrial, bulk, and macro-level electrical resistance specifications 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 megohms (MΩ) and microhms (µΩ), keep full floating-point precision (1 MΩ = 1e+12 µΩ; 1 µΩ = 1e-12 MΩ) during intermediate calculations and round only the final microhm figure to match your instrument tolerance.
