Convert electrical units by family and calculate voltage, current, resistance, power, and energy with context values.
Context values
Some unit families need one extra value for a physically accurate result.
Millivolt is 0.001 volt units.
Result = input x 0.1 / 0.001.

About Converting Decivolts to Millivolts
Decivolt 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: Decivolt is 0.1 volt units, and millivolt is 0.001 volt units.
Formula
millivolts = decivolts × 100
This factor comes from each unit's defined relationship to the category's base unit: 1 decivolt equals 0.1 base units, and 1 millivolt equals 0.001 base units, so dividing one by the other gives the direct decivolt-to-millivolt factor of 100.
Simple example
1 dV × 100 = 100 mV
1 decivolt = 100 millivolts.
Real-world example
120 dV × 100 = 12,000 mV
120 decivolts = 12,000 millivolts.

Reverse conversion: Millivolt to Decivolt
100 mV × 0.01 = 1 dV
100 millivolts = 1 decivolt.
decivolts = millivolts × 0.01

Frequently asked questions
How many millivolts are in 1 decivolt?
1 decivolt equals 100 millivolts, using the exact defined conversion factor rather than an estimate.
How do I convert decivolt to millivolt?
Multiply the decivolt value by 100. The converter above does this instantly to whatever precision you set.
How do I convert millivolt back to decivolt?
Use the reverse factor: 1 millivolt equals 0.01 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 millivolt?
Millivolt (mV) is a unit of electricity.
Is the decivolt to millivolt conversion exact?
Yes. Both decivolt and millivolt are defined by fixed standards rather than physical artifacts, so the factor of 100 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.
