Milliohm to Microohm (mΩ to μΩ)
Convert mΩ to μΩ — Electric Resistance converter
Also written as mohm to uohm.
One milliohm equals 1000 μΩ, so to convert milliohms to microohms you multiply the value by 1000. A milliohm is larger than a microohm — going the other way, 1 μΩ = 0.001 mΩ. For example, 10 mΩ = 10000 μΩ and 50 mΩ = 50000 μΩ.
1 mΩ = 1000 μΩ
Milliohm to Microohm formula
1 Milliohm = 1000 μΩ
Worked examples
- 25 mΩ = 25000 μΩ
- 100 mΩ = 100000 μΩ

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 mΩ = 1000 μΩ.
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.
