About Converting Decihenrys to Millihenrys
Decihenry 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: Decihenry is 0.1 henry units, and millihenry is 0.001 henry units.
Formula
millihenrys = decihenrys × 100
This factor comes from each unit's defined relationship to the category's base unit: 1 decihenry equals 0.1 base units, and 1 millihenry equals 0.001 base units, so dividing one by the other gives the direct decihenry-to-millihenry factor of 100.
Simple example
1 dH × 100 = 100 mH
1 decihenry = 100 millihenrys.
Real-world example
120 dH × 100 = 12,000 mH
120 decihenrys = 12,000 millihenrys.

Frequently asked questions
How many millihenrys are in 1 decihenry?
1 decihenry equals 100 millihenrys, using the exact defined conversion factor rather than an estimate.
How do I convert decihenry to millihenry?
Multiply the decihenry value by 100. The converter above does this instantly to whatever precision you set.
How do I convert millihenry back to decihenry?
Use the reverse factor: 1 millihenry equals 0.01 decihenrys. You can also use the swap control in the converter above to flip the direction instantly.
What is a decihenry?
Decihenry (dH) is a unit of electricity.
What is a millihenry?
Millihenry (mH) is a unit of electricity.
Is the decihenry to millihenry conversion exact?
Yes. Both decihenry and millihenry are defined by fixed standards rather than physical artifacts, so the factor of 100 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.
