ohm inch to milliohm meter
Convert ohm inch (Ω·in) to milliohm meter (mΩ·m). Use an editable electrical resistivity converter, conversion formula, and reference table.
1 Ω·in = 25.4 mΩ·m
Conversion formula
One ohm inch equals 25.4 milliohm meter. Multiply your value in ohm inch by this factor to get milliohm meter. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 ohm inch:5 × 25.4 = 127 mΩ·m

About these measurements
Resistivity describes a material’s resistance independent of shape.
The base reference used here is the ohm meter. One ohm inch is 0.0254 base units; one milliohm meter is 0.001 base units.
Important distinctions
Compound units must match the quantity and dimension. Temperature intervals use size factors rather than temperature offsets. Calorie and BTU entries use the explicit definitions shown.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert Ω·in to mΩ·m?
Multiply the quantity in Ω·in by 25.4. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the milliohm meter to ohm inch converter.
