About Converting Kilohenrys to Millihenrys
Kilohenry and Millihenry 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: Kilohenry is 1000 henry units, and millihenry is 0.001 henry units.
Formula
millihenrys = kilohenrys × 1000000
This factor comes from each unit's defined relationship to the category's base unit: 1 kilohenry equals 1000 base units, and 1 millihenry equals 0.001 base units, so dividing one by the other gives the direct kilohenry-to-millihenry factor of 1000000.
Simple example
1 kH × 1000000 = 1,000,000 mH
1 kilohenry = 1,000,000 millihenrys.
Real-world example
120 kH × 1000000 = 120,000,000 mH
120 kilohenrys = 120,000,000 millihenrys.
Conversion table
| Kilohenry (kH) | Millihenry (mH) |
|---|---|
| 1 kH | 1,000,000 mH |
| 5 kH | 5,000,000 mH |
| 12 kH | 12,000,000 mH |
| 24 kH | 24,000,000 mH |

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

Frequently asked questions
How many millihenrys are in 1 kilohenry?
1 kilohenry equals 1,000,000 millihenrys, using the exact defined conversion factor rather than an estimate.
How do I convert kilohenry to millihenry?
Multiply the kilohenry value by 1000000. The converter above does this instantly to whatever precision you set.
How do I convert millihenry back to kilohenry?
Use the reverse factor: 1 millihenry equals 0.000001 kilohenrys. You can also use the swap control in the converter above to flip the direction instantly.
What is a kilohenry?
Kilohenry (kH) is a unit of electricity.
What is a millihenry?
Millihenry (mH) is a unit of electricity.
Is the kilohenry to millihenry conversion exact?
Yes. Both kilohenry and millihenry are defined by fixed standards rather than physical artifacts, so the factor of 1000000 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.
