Context values
Some unit families need one extra value for a physically accurate result.
Millivolt is 0.001 volt units.
Result = input x 1e+6 / 0.001.

About Converting Megavolts to Millivolts
Megavolt and Millivolt 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 millivolt is 0.001 volt units.
Formula
millivolts = megavolts × 1000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 megavolt equals 1000000 base units, and 1 millivolt equals 0.001 base units, so dividing one by the other gives the direct megavolt-to-millivolt factor of 1000000000.
Simple example
1 MV × 1000000000 = 1,000,000,000 mV
1 megavolt = 1,000,000,000 millivolts.
Real-world example
120 MV × 1000000000 = 120,000,000,000 mV
120 megavolts = 120,000,000,000 millivolts.

Reverse conversion: Millivolt to Megavolt
1 mV × 1e-9 = 1e-9 MV
1 millivolt = 1e-9 megavolts.
megavolts = millivolts × 1e-9

Frequently asked questions
How many millivolts are in 1 megavolt?
1 megavolt equals 1,000,000,000 millivolts, using the exact defined conversion factor rather than an estimate.
How do I convert megavolt to millivolt?
Multiply the megavolt value by 1000000000. The converter above does this instantly to whatever precision you set.
How do I convert millivolt back to megavolt?
Use the reverse factor: 1 millivolt equals 1e-9 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 millivolt?
Millivolt (mV) is a unit of electricity.
Is the megavolt to millivolt conversion exact?
Yes. Both megavolt and millivolt are defined by fixed standards rather than physical artifacts, so the factor of 1000000000 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.
