Ohm (Ω)
The ohm (Ω) is the SI unit of electrical resistance — one volt per ampere (V/A), the inverse of siemens.
Ohms quantify resistors, wire resistance, input impedance, and any opposition to current flow in circuits.

How to convert
Exact conversion factors in both directions, plus a worked example.
1 Ω = 1000000 µΩ
1 µΩ = 0.000001 Ω
To convert ohm to microohm, multiply by 1000000.
To convert microohm to ohm, multiply by 0.000001.
Example: convert 10 Ω to µΩ
10 × 1000000 = 10000000 µΩ
About these units
Short background on the units used in this conversion.
Microohm (µΩ)
The microohm (µΩ) equals 10⁻⁶ ohm — used for shunt resistors, busbar resistance, and contact resistance.
Microohms quantify very low resistances in current sensing, welding, and precision four-wire measurements.
Frequently asked questions
How many microohms are in one ohm?
One ohm equals 1,000,000 microohms. Multiply your ohms value by 1,000,000 to convert to microohms.
What is the conversion formula?
µΩ = Ω × 1,000,000The reverse is
Ω = µΩ × 0.000001, using the same exact factors as this converter.Is this Ohm to Microohm converter private?
