About Converting Gigahenrys to Petahenrys
Gigahenry and Petahenry 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: Gigahenry is 1000000000 henry units, and petahenry is 1000000000000000 henry units.
Formula
petahenrys = gigahenrys × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 gigahenry equals 1000000000 base units, and 1 petahenry equals 1e+15 base units, so dividing one by the other gives the direct gigahenry-to-petahenry factor of 0.000001.
Simple example
1 GH × 0.000001 = 0.000001 PH
1 gigahenry = 0.000001 petahenrys.
Real-world example
120 GH × 0.000001 = 0.00012 PH
120 gigahenrys = 0.00012 petahenrys.

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