How to Convert Volts to Millivolts

conversion scale showing volts and equivalent millivolts voltage values

To convert a volt measurement to a millivolt measurement, multiply the voltage by the conversion ratio. One volt is equal to 1,000 millivolts, so use this simple formula to convert:

millivolts = volts × 1,000

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

For example, here's how to convert 5 volts to millivolts using the formula above.

5 V = (5 × 1,000) = 5,000 mV

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

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.

V_V = I_A × R_Ω

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

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.
