About Converting Gigavolts to Attovolts
Gigavolt and Attovolt 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: Gigavolt is 1000000000 volt units, and attovolt is 1e-18 volt units.
Formula
attovolts = gigavolts × 1e+27
This factor comes from each unit's defined relationship to the category's base unit: 1 gigavolt equals 1000000000 base units, and 1 attovolt equals 1e-18 base units, so dividing one by the other gives the direct gigavolt-to-attovolt factor of 1e+27.
Simple example
1 GV × 1e+27 = 1e+27 aV
1 gigavolt = 1e+27 attovolts.
Real-world example
120 GV × 1e+27 = 1.2e+29 aV
120 gigavolts = 1.2e+29 attovolts.

Frequently asked questions
How many attovolts are in 1 gigavolt?
1 gigavolt equals 1e+27 attovolts, using the exact defined conversion factor rather than an estimate.
How do I convert gigavolt to attovolt?
Multiply the gigavolt value by 1e+27. The converter above does this instantly to whatever precision you set.
How do I convert attovolt back to gigavolt?
Use the reverse factor: 1 attovolt equals 1e-27 gigavolts. You can also use the swap control in the converter above to flip the direction instantly.
What is a gigavolt?
Gigavolt (GV) is a unit of electricity.
What is a attovolt?
Attovolt (aV) is a unit of electricity.
Is the gigavolt to attovolt conversion exact?
Yes. Both gigavolt and attovolt are defined by fixed standards rather than physical artifacts, so the factor of 1e+27 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.
