Microohm to Milliohm (μΩ to mΩ)
Convert μΩ to mΩ — Electric Resistance converter
Also written as uohm to mohm.
One microohm equals 0.001 mΩ, so to convert microohms to milliohms you multiply the value by 0.001. A microohm is smaller than a milliohm — going the other way, 1 mΩ = 1000 μΩ. For example, 10 μΩ = 0.01 mΩ and 50 μΩ = 0.05 mΩ.
1 μΩ = 0.001 mΩ
Microohm to Milliohm formula
1 Microohm = 0.001 mΩ
Worked examples
- 25 μΩ = 0.025 mΩ
- 100 μΩ = 0.1 mΩ

Resistor notation and where each scale is used
Resistor values are usually written without a decimal point, because decimal points disappear on smudged schematics and photocopies. BS 1852 notation puts the multiplier where the point would go: 4R7 is 4.7 Ω, 4K7 is 4.7 kΩ, and 4M7 is 4.7 MΩ. A value written plainly as "4.7" with no unit is ambiguous and worth checking.
The scale is decimal throughout: 1 MΩ = 1,000 kΩ = 1,000,000 Ω, and 1 Ω = 1,000 mΩ = 1,000,000 µΩ. On this page, 1 μΩ = 0.001 mΩ.
Milliohms and microohms are the domain of shunts, contact resistance, busbars and battery internal resistance. At these values the resistance of your test leads is no longer negligible, which is why they are measured with a four-wire (Kelvin) connection rather than a standard multimeter.
