How to Convert Millivolts to Volts

conversion scale showing millivolts and equivalent volts voltage values

To convert a millivolt measurement to a volt measurement, multiply the voltage by the conversion ratio. One millivolt is equal to 0.001 volts, so use this simple formula to convert:

volts = millivolts × 0.001

The voltage in volts is equal to the millivolts multiplied by 0.001.

For example, here's how to convert 5 millivolts to volts using the formula above.
5 mV = (5 × 0.001) = 0.005 V

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

Millivolts

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.

Volts

Voltage is a measurement of electromotive force and the electrical potential difference between two points of a conductor. 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.
