About Converting Millihenrys to Kilohenrys
Millihenry and Kilohenry 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 kilohenry is 1000 henry units.
Formula
kilohenrys = millihenrys × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 millihenry equals 0.001 base units, and 1 kilohenry equals 1000 base units, so dividing one by the other gives the direct millihenry-to-kilohenry factor of 0.000001.
Simple example
1 mH × 0.000001 = 0.000001 kH
1 millihenry = 0.000001 kilohenrys.
Real-world example
120 mH × 0.000001 = 0.00012 kH
120 millihenrys = 0.00012 kilohenrys.

Reverse conversion: Kilohenry to Millihenry
0.000001 kH × 1000000 = 1 mH
0.000001 kilohenrys = 1 millihenry.
millihenrys = kilohenrys × 1000000

Frequently asked questions
How many kilohenrys are in 1 millihenry?
1 millihenry equals 0.000001 kilohenrys, using the exact defined conversion factor rather than an estimate.
How do I convert millihenry to kilohenry?
Multiply the millihenry value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert kilohenry back to millihenry?
Use the reverse factor: 1 kilohenry equals 1,000,000 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 kilohenry?
Kilohenry (kH) is a unit of electricity.
Is the millihenry to kilohenry conversion exact?
Yes. Both millihenry and kilohenry 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.
