Volts to Millivolts Conversion

Volts and millivolts are used to measure voltage or potential difference, and their conversions are simple and straightforward - one just has to remember that "m" stands for "milli," which is, according to the SI prefixes table, 10-3 (one thousandth) of the main value.

How To Convert Volts (V) to Millivolts (mV)

"m" stands for "milli" and means "one thousandth."  Thus, one volt equals 1000 millivolts:

1V = 1000 mV

For example, if You want to convert 15.34V to millivolts, You can write:

U(V) = 15.34V = 15.34 * 1000 mV = 15340 mV

Volts (V) to Millivolts (mV) Conversion Table

The following chart contains the most common volts (V) values converted to millivolts (mV)

Volts (V)
Millivolts (mV)
0.01 10
0.1 100
0.25 250
0.5 500
1 1000
2 2000
3 3000
5 5000
10 10000
50 50000
100 100000

If You wish to convert values that are not in the table, please use the volts to millivolts conversion calculator.

1V to mV Conversion

If You want to convert 1V to millivolts, you can either calculate it or check the table.


1V = 1 * 1000 mV = 1000 mV

So, the potential difference (or voltage) of 1V equals 1000 mV - just divide it by 1000.

Short Intro to Volts

The concept of voltage, often expressed in volts, is a fundamental element in the field of electricity and electronics.

The volt, symbolized as 'V,' is the unit of electric potential and potential difference (voltage) in the International System of Units (SI). One volt is defined as the potential difference across a conductor when a current of one ampere dissipates one watt of power (Ohm's Law).

In simpler terms, it represents the force that drives an electric current between two points, just like water pressure difference drives a water flow between two ends of a water hose.

The term 'volt' is derived from the name of the Italian physicist Alessandro Volta, who is credited with inventing the Voltaic Pile, one of the earliest known batteries, in the 1800s.

This invention was very important in the development of electricity as a practical power source and laid the groundwork for modern electrical engineering. Volta's work was instrumental in understanding electromotive force, a precursor concept to voltage.

In practical applications, volts are used to quantify the electric potential required to power various devices and systems.

For example, common household batteries are typically rated at 1.5 volts, whereas car batteries usually operate at around 12 volts. On a larger scale, electrical utilities deliver power to homes and businesses at significantly higher voltages, which are then stepped down for safe usage.

The significance of the volt lies not just in its measurement of electric potential but also in its role in the broader understanding of electrical phenomena. Its standardization as a unit has been crucial in the development of technologies ranging from the simplest circuits to complex power grids, solidifying its place as a cornerstone in the field of electrical science.
