About Converting Decivolts to Megavolts
Decivolt 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: Decivolt is 0.1 volt units, and megavolt is 1000000 volt units.
Formula
megavolts = decivolts × 1e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 decivolt equals 0.1 base units, and 1 megavolt equals 1000000 base units, so dividing one by the other gives the direct decivolt-to-megavolt factor of 1e-7.
Simple example
1 dV × 1e-7 = 1e-7 MV
1 decivolt = 1e-7 megavolts.
Real-world example
120 dV × 1e-7 = 0.000012 MV
120 decivolts = 0.000012 megavolts.

Reverse conversion: Megavolt to Decivolt
1e-7 MV × 10000000 = 1 dV
1e-7 megavolts = 1 decivolts.
decivolts = megavolts × 10000000

Frequently asked questions
How many megavolts are in 1 decivolt?
1 decivolt equals 1e-7 megavolts, using the exact defined conversion factor rather than an estimate.
How do I convert decivolt to megavolt?
Multiply the decivolt value by 1e-7. The converter above does this instantly to whatever precision you set.
How do I convert megavolt back to decivolt?
Use the reverse factor: 1 megavolt equals 10,000,000 decivolts. You can also use the swap control in the converter above to flip the direction instantly.
What is a decivolt?
Decivolt (dV) is a unit of electricity.
What is a megavolt?
Megavolt (MV) is a unit of electricity.
Is the decivolt to megavolt conversion exact?
Yes. Both decivolt and megavolt are defined by fixed standards rather than physical artifacts, so the factor of 1e-7 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.
