About Converting Megavolts to Gigavolts
Megavolt 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: Megavolt is 1000000 volt units, and gigavolt is 1000000000 volt units.
Formula
gigavolts = megavolts × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 megavolt equals 1000000 base units, and 1 gigavolt equals 1000000000 base units, so dividing one by the other gives the direct megavolt-to-gigavolt factor of 0.001.
Simple example
1 MV × 0.001 = 0.001 GV
1 megavolt = 0.001 gigavolts.
Real-world example
120 MV × 0.001 = 0.12 GV
120 megavolts = 0.12 gigavolts.

Frequently asked questions
How many gigavolts are in 1 megavolt?
1 megavolt equals 0.001 gigavolts, using the exact defined conversion factor rather than an estimate.
How do I convert megavolt to gigavolt?
Multiply the megavolt value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert gigavolt back to megavolt?
Use the reverse factor: 1 gigavolt equals 1,000 megavolts. You can also use the swap control in the converter above to flip the direction instantly.
What is a megavolt?
Megavolt (MV) is a unit of electricity.
What is a gigavolt?
Gigavolt (GV) is a unit of electricity.
Is the megavolt to gigavolt conversion exact?
Yes. Both megavolt and gigavolt are defined by fixed standards rather than physical artifacts, so the factor of 0.001 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.
