About Converting Hectovolts to Megavolts
Hectovolt and Megavolt 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: Hectovolt is 100 volt units, and megavolt is 1000000 volt units.
Formula
megavolts = hectovolts × 0.0001
This factor comes from each unit's defined relationship to the category's base unit: 1 hectovolt equals 100 base units, and 1 megavolt equals 1000000 base units, so dividing one by the other gives the direct hectovolt-to-megavolt factor of 0.0001.
Simple example
1 hV × 0.0001 = 0.0001 MV
1 hectovolt = 0.0001 megavolts.
Real-world example
120 hV × 0.0001 = 0.012 MV
120 hectovolts = 0.012 megavolts.

Reverse conversion: Megavolt to Hectovolt
0.0001 MV × 10000 = 1 hV
0.0001 megavolts = 1 hectovolt.
hectovolts = megavolts × 10000

Frequently asked questions
How many megavolts are in 1 hectovolt?
1 hectovolt equals 0.0001 megavolts, using the exact defined conversion factor rather than an estimate.
How do I convert hectovolt to megavolt?
Multiply the hectovolt value by 0.0001. The converter above does this instantly to whatever precision you set.
How do I convert megavolt back to hectovolt?
Use the reverse factor: 1 megavolt equals 10,000 hectovolts. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectovolt?
Hectovolt (hV) is a unit of electricity.
What is a megavolt?
Megavolt (MV) is a unit of electricity.
Is the hectovolt to megavolt conversion exact?
Yes. Both hectovolt and megavolt are defined by fixed standards rather than physical artifacts, so the factor of 0.0001 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.
