About Converting Petaohms to Exaohms
Petaohm and Exaohm 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: Petaohm is 1000000000000000 ohm units, and exaohm is 1000000000000000000 ohm units.
Formula
exaohms = petaohms × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 petaohm equals 1e+15 base units, and 1 exaohm equals 1e+18 base units, so dividing one by the other gives the direct petaohm-to-exaohm factor of 0.001.
Simple example
1 POhm × 0.001 = 0.001 EOhm
1 petaohm = 0.001 exaohms.
Real-world example
120 POhm × 0.001 = 0.12 EOhm
120 petaohms = 0.12 exaohms.

Reverse conversion: Exaohm to Petaohm
0.001 EOhm × 1000 = 1 POhm
0.001 exaohms = 1 petaohm.
petaohms = exaohms × 1000

Frequently asked questions
How many exaohms are in 1 petaohm?
1 petaohm equals 0.001 exaohms, using the exact defined conversion factor rather than an estimate.
How do I convert petaohm to exaohm?
Multiply the petaohm value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert exaohm back to petaohm?
Use the reverse factor: 1 exaohm equals 1,000 petaohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a petaohm?
Petaohm (POhm) is a unit of electricity.
What is a exaohm?
Exaohm (EOhm) is a unit of electricity.
Is the petaohm to exaohm conversion exact?
Yes. Both petaohm and exaohm 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.
