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.
Decavolt is 10 volt units.
Result = input x 0.001 / 10.

About Converting Millivolts to Decavolts
Millivolt and Decavolt 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: Millivolt is 0.001 volt units, and decavolt is 10 volt units.
Formula
decavolts = millivolts × 0.0001
This factor comes from each unit's defined relationship to the category's base unit: 1 millivolt equals 0.001 base units, and 1 decavolt equals 10 base units, so dividing one by the other gives the direct millivolt-to-decavolt factor of 0.0001.
Simple example
1 mV × 0.0001 = 0.0001 daV
1 millivolt = 0.0001 decavolts.
Real-world example
120 mV × 0.0001 = 0.012 daV
120 millivolts = 0.012 decavolts.

Reverse conversion: Decavolt to Millivolt
0.0001 daV × 10000 = 1 mV
0.0001 decavolts = 1 millivolt.
millivolts = decavolts × 10000

Frequently asked questions
How many decavolts are in 1 millivolt?
1 millivolt equals 0.0001 decavolts, using the exact defined conversion factor rather than an estimate.
How do I convert millivolt to decavolt?
Multiply the millivolt value by 0.0001. The converter above does this instantly to whatever precision you set.
How do I convert decavolt back to millivolt?
Use the reverse factor: 1 decavolt equals 10,000 millivolts. You can also use the swap control in the converter above to flip the direction instantly.
What is a millivolt?
Millivolt (mV) is a unit of electricity.
What is a decavolt?
Decavolt (daV) is a unit of electricity.
Is the millivolt to decavolt conversion exact?
Yes. Both millivolt and decavolt 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.
