About Converting Hectoohms to Petaohms
Hectoohm and Petaohm 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: Hectoohm is 100 ohm units, and petaohm is 1000000000000000 ohm units.
Formula
petaohms = hectoohms × 1e-13
This factor comes from each unit's defined relationship to the category's base unit: 1 hectoohm equals 100 base units, and 1 petaohm equals 1e+15 base units, so dividing one by the other gives the direct hectoohm-to-petaohm factor of 1e-13.
Simple example
1 hOhm × 1e-13 = 1e-13 POhm
1 hectoohm = 1e-13 petaohms.
Real-world example
120 hOhm × 1e-13 = 1.2e-11 POhm
120 hectoohms = 1.2e-11 petaohms.

Reverse conversion: Petaohm to Hectoohm
1e-13 POhm × 1e+13 = 1 hOhm
1e-13 petaohms = 1 hectoohm.
hectoohms = petaohms × 1e+13

Frequently asked questions
How many petaohms are in 1 hectoohm?
1 hectoohm equals 1e-13 petaohms, using the exact defined conversion factor rather than an estimate.
How do I convert hectoohm to petaohm?
Multiply the hectoohm value by 1e-13. The converter above does this instantly to whatever precision you set.
How do I convert petaohm back to hectoohm?
Use the reverse factor: 1 petaohm equals 1e+13 hectoohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectoohm?
Hectoohm (hOhm) is a unit of electricity.
What is a petaohm?
Petaohm (POhm) is a unit of electricity.
Is the hectoohm to petaohm conversion exact?
Yes. Both hectoohm and petaohm are defined by fixed standards rather than physical artifacts, so the factor of 1e-13 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.
