About Converting Millihenrys to Microhenrys
Millihenry and Microhenry 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: Millihenry is 0.001 henry units, and microhenry is 0.000001 henry units.
Formula
microhenrys = millihenrys × 1000
This factor comes from each unit's defined relationship to the category's base unit: 1 millihenry equals 0.001 base units, and 1 microhenry equals 0.000001 base units, so dividing one by the other gives the direct millihenry-to-microhenry factor of 1000.
Simple example
1 mH × 1000 = 1,000 uH
1 millihenry = 1,000 microhenrys.
Real-world example
120 mH × 1000 = 120,000 uH
120 millihenrys = 120,000 microhenrys.

Reverse conversion: Microhenry to Millihenry
1 uH × 0.001 = 0.001 mH
1 microhenry = 0.001 millihenrys.
millihenrys = microhenrys × 0.001

Frequently asked questions
How many microhenrys are in 1 millihenry?
1 millihenry equals 1,000 microhenrys, using the exact defined conversion factor rather than an estimate.
How do I convert millihenry to microhenry?
Multiply the millihenry value by 1000. The converter above does this instantly to whatever precision you set.
How do I convert microhenry back to millihenry?
Use the reverse factor: 1 microhenry equals 0.001 millihenrys. You can also use the swap control in the converter above to flip the direction instantly.
What is a millihenry?
Millihenry (mH) is a unit of electricity.
What is a microhenry?
Microhenry (uH) is a unit of electricity.
Is the millihenry to microhenry conversion exact?
Yes. Both millihenry and microhenry 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.
