How to Convert Microhm Inches to Ohm Meters
To convert microhm inches to ohm meters, multiply the electrical resistivity by the following conversion ratio: 0.000000025 ohm meters/microhm inch.
Since one microhm inch is equal to 0.000000025 ohm meters, you can use this simple formula to convert:
The electrical resistivity in ohm meters is equal to the electrical resistivity in microhm inches multiplied by 0.000000025.
For example, here's how to convert 5 microhm inches to ohm meters using the formula above.

What Is a Microhm Inch?
A microhm inch is a unit of electrical resistivity equal to 0.000000025 ohm meters (Ω·m), the base unit for electrical resistivity. Equal to 2.54×10⁻⁸ Ω·m. [1]
The microhm inch is classified as a US customary unit of electrical resistivity. Microhm Inches can be abbreviated as µΩ·in; for example, 1 microhm inch can be written as 1 µΩ·in.
In the metric system, "micro" is the standard SI prefix for millionths, or 10⁻⁶. This makes the microhm inch (µΩ·in) a convenient decimal multiple of the ohm meter (Ω·m).
In practice, microhm inches (µΩ·in) are widely used across fine-tolerance laboratory, analytical, and micro-scale electrical resistivity measurements within US customary workflows, engineering documentation, and technical data sheets.
What Is an Ohm Meter?
SI unit of electrical resistivity. It serves as a primary reference unit for measuring electrical resistivity across scientific and practical applications. [2]
The ohm meter is classified as an International System of Units (SI) unit of electrical resistivity. Ohm Meters can be abbreviated as Ω·m; for example, 1 ohm meter can be written as 1 Ω·m.
As the primary coherent reference unit for electrical resistivity in this category, all other electrical resistivity units are mathematically anchored to the ohm meter (Ω·m).
In practice, ohm meters (Ω·m) are widely used across standard electrical resistivity applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
When converting electrical resistivity between microhm inches (µΩ·in) and ohm meters (Ω·m), keep full floating-point precision (1 µΩ·in = 0.000000025 Ω·m; 1 Ω·m = 39,370,078.7401575 µΩ·in) during intermediate calculations and round only the final ohm meter figure to match your instrument tolerance.
