About Converting Centihenrys to Millihenrys
Centihenry 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: Centihenry is 0.01 henry units, and millihenry is 0.001 henry units.
Formula
millihenrys = centihenrys × 10
This factor comes from each unit's defined relationship to the category's base unit: 1 centihenry equals 0.01 base units, and 1 millihenry equals 0.001 base units, so dividing one by the other gives the direct centihenry-to-millihenry factor of 10.
Simple example
1 cH × 10 = 10 mH
1 centihenry = 10 millihenrys.
Real-world example
120 cH × 10 = 1,200 mH
120 centihenrys = 1,200 millihenrys.

Reverse conversion: Millihenry to Centihenry
10 mH × 0.1 = 1 cH
10 millihenrys = 1 centihenry.
centihenrys = millihenrys × 0.1

Frequently asked questions
How many millihenrys are in 1 centihenry?
1 centihenry equals 10 millihenrys, using the exact defined conversion factor rather than an estimate.
How do I convert centihenry to millihenry?
Multiply the centihenry value by 10. The converter above does this instantly to whatever precision you set.
How do I convert millihenry back to centihenry?
Use the reverse factor: 1 millihenry equals 0.1 centihenrys. You can also use the swap control in the converter above to flip the direction instantly.
What is a centihenry?
Centihenry (cH) is a unit of electricity.
What is a millihenry?
Millihenry (mH) is a unit of electricity.
Is the centihenry to millihenry conversion exact?
Yes. Both centihenry and millihenry are defined by fixed standards rather than physical artifacts, so the factor of 10 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.
