About Converting Nanoohms to Gigaohms
Nanoohm and Gigaohm 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: Nanoohm is 1e-9 ohm units, and gigaohm is 1000000000 ohm units.
Formula
gigaohms = nanoohms × 1e-18
This factor comes from each unit's defined relationship to the category's base unit: 1 nanoohm equals 1e-9 base units, and 1 gigaohm equals 1000000000 base units, so dividing one by the other gives the direct nanoohm-to-gigaohm factor of 1e-18.
Simple example
1 nOhm × 1e-18 = 1e-18 GOhm
1 nanoohm = 1e-18 gigaohms.
Real-world example
120 nOhm × 1e-18 = 1.2e-16 GOhm
120 nanoohms = 1.2e-16 gigaohms.

Reverse conversion: Gigaohm to Nanoohm
1e-18 GOhm × 1e+18 = 1 nOhm
1e-18 gigaohms = 1 nanoohm.
nanoohms = gigaohms × 1e+18

Frequently asked questions
How many gigaohms are in 1 nanoohm?
1 nanoohm equals 1e-18 gigaohms, using the exact defined conversion factor rather than an estimate.
How do I convert nanoohm to gigaohm?
Multiply the nanoohm value by 1e-18. The converter above does this instantly to whatever precision you set.
How do I convert gigaohm back to nanoohm?
Use the reverse factor: 1 gigaohm equals 1e+18 nanoohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanoohm?
Nanoohm (nOhm) is a unit of electricity.
What is a gigaohm?
Gigaohm (GOhm) is a unit of electricity.
Is the nanoohm to gigaohm conversion exact?
Yes. Both nanoohm and gigaohm are defined by fixed standards rather than physical artifacts, so the factor of 1e-18 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.
