Context values
Some unit families need one extra value for a physically accurate result.
Henry is the SI unit of inductance.
Result = input x 100 / 1.

About Converting Hectohenrys to Henrys
Hectohenry and Henry 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: Hectohenry is 100 henry units, and henry is the SI unit of inductance.
Formula
henrys = hectohenrys × 100
This factor comes from each unit's defined relationship to the category's base unit: 1 hectohenry equals 100 base units, and 1 henry equals 1 base unit, so dividing one by the other gives the direct hectohenry-to-henry factor of 100.
Simple example
1 hH × 100 = 100 H
1 hectohenry = 100 henrys.
Real-world example
120 hH × 100 = 12,000 H
120 hectohenrys = 12,000 henrys.
Conversion table
| Hectohenry (hH) | Henry (H) |
|---|---|
| 1 hH | 100 H |
| 5 hH | 500 H |
| 12 hH | 1,200 H |
| 24 hH | 2,400 H |

Reverse conversion: Henry to Hectohenry
100 H × 0.01 = 1 hH
100 henrys = 1 hectohenry.
hectohenrys = henrys × 0.01

Understanding the Hectohenry (hH)
Hectohenry is 100 henry units.
Understanding the Henry
Henry (H) measures electrical inductance. The SI derived unit of electrical inductance, equal to one volt-second per ampere. It is classified as a SI derived unit.
Where it's used: Universal — SI derived unit used worldwide
Uses of the Henry today
- Inductor and transformer ratings in electronics
- Motor and generator design calculations
- Circuit filtering and signal-processing design
History of the Henry
The henry is named after Joseph Henry (1797–1878), an American scientist who discovered the electromagnetic phenomenon of self-inductance independently of, and at roughly the same time as, Michael Faraday's related discoveries in England.
Historical origin. Henry was not the invention of a single named person; it developed through the process described above.

Frequently asked questions
How many henrys are in 1 hectohenry?
1 hectohenry equals 100 henrys, using the exact defined conversion factor rather than an estimate.
How do I convert hectohenry to henry?
Multiply the hectohenry value by 100. The converter above does this instantly to whatever precision you set.
How do I convert henry back to hectohenry?
Use the reverse factor: 1 henry equals 0.01 hectohenrys. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectohenry?
Hectohenry (hH) is a unit of electricity.
What is a henry?
Henry (H) measures electrical inductance. The SI derived unit of electrical inductance, equal to one volt-second per ampere. It is classified as a SI derived unit.
Is the hectohenry to henry conversion exact?
Yes. Both hectohenry and henry 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.
