Ohm to Microohm (Ω to μΩ)
Convert Ω to μΩ — Electric Resistance converter
Also written as ohm to uohm.
One ohm equals 1000000 μΩ, so to convert ohms to microohms you multiply the value by 1000000. A ohm is larger than a microohm — going the other way, 1 μΩ = 0.000001 Ω. For example, 10 Ω = 10000000 μΩ and 50 Ω = 50000000 μΩ.
1 Ω = 1000000 μΩ
Ohm to Microohm formula
1 Ohm = 1000000 μΩ
Worked examples
- 25 Ω = 25000000 μΩ
- 100 Ω = 100000000 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 Ω = 1000000 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.
