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.
Kilovolt is 1000 volt units.
Result = input x 0.001 / 1000.

About Converting Millivolts to Kilovolts
Millivolt and Kilovolt 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 kilovolt is 1000 volt units.
Formula
kilovolts = millivolts × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 millivolt equals 0.001 base units, and 1 kilovolt equals 1000 base units, so dividing one by the other gives the direct millivolt-to-kilovolt factor of 0.000001.
Simple example
1 mV × 0.000001 = 0.000001 kV
1 millivolt = 0.000001 kilovolts.
Real-world example
120 mV × 0.000001 = 0.00012 kV
120 millivolts = 0.00012 kilovolts.

Reverse conversion: Kilovolt to Millivolt
0.000001 kV × 1000000 = 1 mV
0.000001 kilovolts = 1 millivolt.
millivolts = kilovolts × 1000000

Frequently asked questions
How many kilovolts are in 1 millivolt?
1 millivolt equals 0.000001 kilovolts, using the exact defined conversion factor rather than an estimate.
How do I convert millivolt to kilovolt?
Multiply the millivolt value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert kilovolt back to millivolt?
Use the reverse factor: 1 kilovolt equals 1,000,000 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 kilovolt?
Kilovolt (kV) is a unit of electricity.
Is the millivolt to kilovolt conversion exact?
Yes. Both millivolt and kilovolt are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 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.
