How many mV in 1 V?
The answer is 1000.

We assume you are converting between **millivolt** and **volt**.

You can view more details on each measurement unit:

mV or
V

The SI derived unit for **voltage** is the volt.

1 mV is equal to 0.001 volt.

Note that rounding errors may occur, so always check the results.

Use this page to learn how to convert between millivolts and volts.

Type in your own numbers in the form to convert the units!

1 mV to V = 0.001 V

10 mV to V = 0.01 V

50 mV to V = 0.05 V

100 mV to V = 0.1 V

200 mV to V = 0.2 V

500 mV to V = 0.5 V

1000 mV to V = 1 V

You can do the reverse unit conversion from V to mV, or enter any two units below:

mV to yoctovolt

mV to decivolt

mV to gigavolt

mV to hectovolt

mV to exavolt

mV to megavolt

mV to attovolt

mV to zeptovolt

mV to centivolt

mV to abvolt

The SI prefix "milli" represents a factor of
10^{-3}, or in exponential notation, 1E-3.

So 1 millivolt = 10^{-3} volts.

The definition of a volt is as follows:

The volt (symbol: V) is the SI derived unit of electric potential difference or electromotive force, commonly known as voltage. It is named in honor of the Lombard physicist Alessandro Volta (1745–1827), who invented the voltaic pile, the first chemical battery.

The volt is defined as the potential difference across a conductor when a current of one ampere dissipates one watt of power.[3] Hence, it is the base SI representation m^{2} · kg · s^{-3} · A^{-1}, which can be equally represented as one joule of energy per coulomb of charge, J/C.
