How to Convert Millivolts to Volts

To convert a millivolt measurement to a volt measurement, divide the voltage by the conversion ratio.

Since one volt is equal to 1,000 millivolts, you can use this simple formula to convert:

volts = millivolts ÷ 1,000

The voltage in volts is equal to the millivolts divided by 1,000.

For example, here's how to convert 5,000 millivolts to volts using the formula above.
5,000 mV = (5,000 ÷ 1,000) = 5 V

Millivolts and volts are both units used to measure voltage. Keep reading to learn more about each unit of measure.


One millivolt is equal to 1/1,000 of a volt, which is the potential difference that would move one ampere of current against one ohm of resistance.

The millivolt is a multiple of the volt, which is the SI derived unit for voltage. In the metric system, "milli" is the prefix for 10-3. Millivolts can be abbreviated as mV; for example, 1 millivolt can be written as 1 mV.


Voltage is a measurement of electromotive force and the electrical potential difference between two points of a conductor.[1] One volt is equal to the potential difference that would move one ampere of current against one ohm of resistance.

The volt is the SI derived unit for voltage in the metric system. Volts can be abbreviated as V; for example, 1 volt can be written as 1 V.

Ohm's Law states the current between two points on a conductor is proportional to the voltage and inversely proportional to the resistance. Using Ohm's Law, it's possible to express the potential difference in volts as an expression using current and resistance.

VV = IA × R

The potential difference in volts is equal to the current in amperes times the resistance in ohms.
