About Converting Millivolts to Gigavolts
Millivolt and Gigavolt 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: Millivolt is 0.001 volt units, and gigavolt is 1000000000 volt units.
Formula
gigavolts = millivolts × 1e-12
This factor comes from each unit's defined relationship to the category's base unit: 1 millivolt equals 0.001 base units, and 1 gigavolt equals 1000000000 base units, so dividing one by the other gives the direct millivolt-to-gigavolt factor of 1e-12.
Simple example
1 mV × 1e-12 = 1e-12 GV
1 millivolt = 1e-12 gigavolts.
Real-world example
120 mV × 1e-12 = 1.2e-10 GV
120 millivolts = 1.2e-10 gigavolts.

Reverse conversion: Gigavolt to Millivolt
1e-12 GV × 1e+12 = 1 mV
1e-12 gigavolts = 1 millivolt.
millivolts = gigavolts × 1e+12

Frequently asked questions
How many gigavolts are in 1 millivolt?
1 millivolt equals 1e-12 gigavolts, using the exact defined conversion factor rather than an estimate.
How do I convert millivolt to gigavolt?
Multiply the millivolt value by 1e-12. The converter above does this instantly to whatever precision you set.
How do I convert gigavolt back to millivolt?
Use the reverse factor: 1 gigavolt equals 1e+12 millivolts. You can also use the swap control in the converter above to flip the direction instantly.
What is a millivolt?
Millivolt (mV) is a unit of electricity.
What is a gigavolt?
Gigavolt (GV) is a unit of electricity.
Is the millivolt to gigavolt conversion exact?
Yes. Both millivolt and gigavolt 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.
