About Converting Petaohms to Zettaohms
Petaohm and Zettaohm 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 zettaohm is 1e+21 ohm units.
Formula
zettaohms = petaohms × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 petaohm equals 1e+15 base units, and 1 zettaohm equals 1e+21 base units, so dividing one by the other gives the direct petaohm-to-zettaohm factor of 0.000001.
Simple example
1 POhm × 0.000001 = 0.000001 ZOhm
1 petaohm = 0.000001 zettaohms.
Real-world example
120 POhm × 0.000001 = 0.00012 ZOhm
120 petaohms = 0.00012 zettaohms.

Reverse conversion: Zettaohm to Petaohm
0.000001 ZOhm × 1000000 = 1 POhm
0.000001 zettaohms = 1 petaohm.
petaohms = zettaohms × 1000000

Frequently asked questions
How many zettaohms are in 1 petaohm?
1 petaohm equals 0.000001 zettaohms, using the exact defined conversion factor rather than an estimate.
How do I convert petaohm to zettaohm?
Multiply the petaohm value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert zettaohm back to petaohm?
Use the reverse factor: 1 zettaohm equals 1,000,000 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 zettaohm?
Zettaohm (ZOhm) is a unit of electricity.
Is the petaohm to zettaohm conversion exact?
Yes. Both petaohm and zettaohm 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.
