Context values
Some unit families need one extra value for a physically accurate result.
Volt is the SI unit of electric potential.
Result = input x 0.1 / 1.

About Converting Decivolts to Volts
Decivolt and Volt 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 volt is the SI unit of electric potential.
Formula
volts = decivolts × 0.1
This factor comes from each unit's defined relationship to the category's base unit: 1 decivolt equals 0.1 base units, and 1 volt equals 1 base unit, so dividing one by the other gives the direct decivolt-to-volt factor of 0.1.
Simple example
1 dV × 0.1 = 0.1 V
1 decivolt = 0.1 volts.
Real-world example
120 dV × 0.1 = 12 V
120 decivolts = 12 volts.

Reverse conversion: Volt to Decivolt
0.1 V × 10 = 1 dV
0.1 volts = 1 decivolt.
decivolts = volts × 10

Understanding the Decivolt (dV)
Decivolt is 0.1 volt units.
Understanding the Volt
Volt (V) measures electric potential. The SI derived unit of electric potential difference, equal to one joule of energy per coulomb of charge. It is classified as a SI derived unit.
Where it's used: Universal — SI derived unit used worldwide
Uses of the Volt today
- Household and automotive electrical system ratings (120V/240V mains, 12V/24V batteries)
- Battery and power-supply specifications
- Electronics design
History of the Volt
The volt is named after Alessandro Volta (1745–1827), an Italian physicist who invented the voltaic pile in 1800 — the first device able to produce a steady electric current, and the direct ancestor of the modern battery.
Historical origin. Volt was not the invention of a single named person; it developed through the process described above.

Frequently asked questions
How many volts are in 1 decivolt?
1 decivolt equals 0.1 volts, using the exact defined conversion factor rather than an estimate.
How do I convert decivolt to volt?
Multiply the decivolt value by 0.1. The converter above does this instantly to whatever precision you set.
How do I convert volt back to decivolt?
Use the reverse factor: 1 volt equals 10 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 volt?
Volt (V) measures electric potential. The SI derived unit of electric potential difference, equal to one joule of energy per coulomb of charge. It is classified as a SI derived unit.
Is the decivolt to volt conversion exact?
Yes. Both decivolt and volt are defined by fixed standards rather than physical artifacts, so the factor of 0.1 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.
