About Converting Gigaohms to Zettaohms
Gigaohm 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: Gigaohm is 1000000000 ohm units, and zettaohm is 1e+21 ohm units.
Formula
zettaohms = gigaohms × 1e-12
This factor comes from each unit's defined relationship to the category's base unit: 1 gigaohm equals 1000000000 base units, and 1 zettaohm equals 1e+21 base units, so dividing one by the other gives the direct gigaohm-to-zettaohm factor of 1e-12.
Simple example
1 GOhm × 1e-12 = 1e-12 ZOhm
1 gigaohm = 1e-12 zettaohms.
Real-world example
120 GOhm × 1e-12 = 1.2e-10 ZOhm
120 gigaohms = 1.2e-10 zettaohms.

Reverse conversion: Zettaohm to Gigaohm
1e-12 ZOhm × 1e+12 = 1 GOhm
1e-12 zettaohms = 1 gigaohm.
gigaohms = zettaohms × 1e+12

Frequently asked questions
How many zettaohms are in 1 gigaohm?
1 gigaohm equals 1e-12 zettaohms, using the exact defined conversion factor rather than an estimate.
How do I convert gigaohm to zettaohm?
Multiply the gigaohm value by 1e-12. The converter above does this instantly to whatever precision you set.
How do I convert zettaohm back to gigaohm?
Use the reverse factor: 1 zettaohm equals 1e+12 gigaohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a gigaohm?
Gigaohm (GOhm) is a unit of electricity.
What is a zettaohm?
Zettaohm (ZOhm) is a unit of electricity.
Is the gigaohm to zettaohm conversion exact?
Yes. Both gigaohm and zettaohm are defined by fixed standards rather than physical artifacts, so the factor of 1e-12 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.
