About Converting Megahenrys to Gigahenrys
Megahenry and Gigahenry 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: Megahenry is 1000000 henry units, and gigahenry is 1000000000 henry units.
Formula
gigahenrys = megahenrys × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 megahenry equals 1000000 base units, and 1 gigahenry equals 1000000000 base units, so dividing one by the other gives the direct megahenry-to-gigahenry factor of 0.001.
Simple example
1 MH × 0.001 = 0.001 GH
1 megahenry = 0.001 gigahenrys.
Real-world example
120 MH × 0.001 = 0.12 GH
120 megahenrys = 0.12 gigahenrys.

Frequently asked questions
How many gigahenrys are in 1 megahenry?
1 megahenry equals 0.001 gigahenrys, using the exact defined conversion factor rather than an estimate.
How do I convert megahenry to gigahenry?
Multiply the megahenry value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert gigahenry back to megahenry?
Use the reverse factor: 1 gigahenry equals 1,000 megahenrys. You can also use the swap control in the converter above to flip the direction instantly.
What is a megahenry?
Megahenry (MH) is a unit of electricity.
What is a gigahenry?
Gigahenry (GH) is a unit of electricity.
Is the megahenry to gigahenry conversion exact?
Yes. Both megahenry and gigahenry are defined by fixed standards rather than physical artifacts, so the factor of 0.001 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.
