About Converting Microohms to Ohms
Microohm and Ohm both belong to the electricity family — voltage, current, resistance, power, or energy — units that show up constantly when working across the different standards used by household wiring (120V/240V depending on region), automotive electrical systems (12V/24V), and electronics design. Specifically: Microohm is 0.000001 ohm units, and ohm is the SI unit of electrical resistance.
Formula
ohms = microohms × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 microohm equals 0.000001 base units, and 1 ohm equals 1 base unit, so dividing one by the other gives the direct microohm-to-ohm factor of 0.000001.
Simple example
1 uOhm × 0.000001 = 0.000001 Ohm
1 microohm = 0.000001 ohms.
Real-world example
120 uOhm × 0.000001 = 0.00012 Ohm
120 microohms = 0.00012 ohms.

Reverse conversion: Ohm to Microohm
0.000001 Ohm × 1000000 = 1 uOhm
0.000001 ohms = 1 microohm.
microohms = ohms × 1000000

Understanding the Microohm (uOhm)
Microohm is 0.000001 ohm units.
Understanding the Ohm
Ohm (Ohm) measures electrical resistance. The SI derived unit of electrical resistance, equal to one volt per ampere. It is classified as a SI derived unit.
Where it's used: Universal — SI derived unit used worldwide
Uses of the Ohm today
- Resistor and circuit-component ratings
- Electrical wiring and grounding specifications
- Audio equipment impedance ratings
History of the Ohm
The ohm is named after Georg Simon Ohm (1789–1854), a German physicist who published Ohm's law in 1827, describing the relationship between voltage, current, and resistance (V = I × R) — the relationship the unit itself is defined through.
Historical origin. Ohm was not the invention of a single named person; it developed through the process described above.

Frequently asked questions
How many ohms are in 1 microohm?
1 microohm equals 0.000001 ohms, using the exact defined conversion factor rather than an estimate.
How do I convert microohm to ohm?
Multiply the microohm value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert ohm back to microohm?
Use the reverse factor: 1 ohm equals 1,000,000 microohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a microohm?
Microohm (uOhm) is a unit of electricity.
What is a ohm?
Ohm (Ohm) measures electrical resistance. The SI derived unit of electrical resistance, equal to one volt per ampere. It is classified as a SI derived unit.
Is the microohm to ohm conversion exact?
Yes. Both microohm and ohm are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 used above is exact to as many digits as you choose to display.
What's the difference between voltage, current, and resistance?
Voltage (volts) is the electrical potential difference driving current through a circuit. Current (amperes) is the rate of flow of electric charge. Resistance (ohms) is how much a component opposes that flow. They're related by Ohm's law (V = I × R), but they are distinct physical quantities, and this page converts between units of just one of them.
