About Converting Milliohms to Microohms
Milliohm and Microohm 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: Milliohm is 0.001 ohm units, and microohm is 0.000001 ohm units.
Formula
microohms = milliohms × 1000
This factor comes from each unit's defined relationship to the category's base unit: 1 milliohm equals 0.001 base units, and 1 microohm equals 0.000001 base units, so dividing one by the other gives the direct milliohm-to-microohm factor of 1000.
Simple example
1 mOhm × 1000 = 1,000 uOhm
1 milliohm = 1,000 microohms.
Real-world example
120 mOhm × 1000 = 120,000 uOhm
120 milliohms = 120,000 microohms.

Frequently asked questions
How many microohms are in 1 milliohm?
1 milliohm equals 1,000 microohms, using the exact defined conversion factor rather than an estimate.
How do I convert milliohm to microohm?
Multiply the milliohm value by 1000. The converter above does this instantly to whatever precision you set.
How do I convert microohm back to milliohm?
Use the reverse factor: 1 microohm equals 0.001 milliohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a milliohm?
Milliohm (mOhm) is a unit of electricity.
What is a microohm?
Microohm (uOhm) is a unit of electricity.
Is the milliohm to microohm conversion exact?
Yes. Both milliohm and microohm are defined by fixed standards rather than physical artifacts, so the factor of 1000 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.
