About Converting Microohms to Milliohms
Microohm and Milliohm 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 milliohm is 0.001 ohm units.
Formula
milliohms = microohms × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 microohm equals 0.000001 base units, and 1 milliohm equals 0.001 base units, so dividing one by the other gives the direct microohm-to-milliohm factor of 0.001.
Simple example
1 uOhm × 0.001 = 0.001 mOhm
1 microohm = 0.001 milliohms.
Real-world example
120 uOhm × 0.001 = 0.12 mOhm
120 microohms = 0.12 milliohms.

Reverse conversion: Milliohm to Microohm
0.001 mOhm × 1000 = 1 uOhm
0.001 milliohms = 1 microohm.
microohms = milliohms × 1000

Frequently asked questions
How many milliohms are in 1 microohm?
1 microohm equals 0.001 milliohms, using the exact defined conversion factor rather than an estimate.
How do I convert microohm to milliohm?
Multiply the microohm value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert milliohm back to microohm?
Use the reverse factor: 1 milliohm equals 1,000 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 milliohm?
Milliohm (mOhm) is a unit of electricity.
Is the microohm to milliohm conversion exact?
Yes. Both microohm and milliohm are defined by fixed standards rather than physical artifacts, so the factor of 0.001 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.
