Millivolt [mV] to Volt [V] Converter

Quick Reference

1 Millivolt (mV) = 0.001 Volt (V)

1 Volt (V) = 1000 Millivolt (mV)

How to Convert Millivolt to Volt

1 mV = 0.001 V
1 V = 1000 mV

To convert Millivolt to Volt, divide the value by 1000 (equivalently, multiply by 0.001). To convert Volt back to Millivolt, multiply by 1000.

Example: convert 10 mV to V:
10 mV = 10 x 0.001 = 0.01 V

Millivolt

Definition: A millivolt (mV) is a unit of electric potential equal to one thousandth (10⁻³) of a volt. It is a subunit of the base unit, the volt, in the International System of Units (SI).

History/origin: The volt is named in honor of Italian physicist Alessandro Volta. The millivolt, as a decimal multiple of the volt, was naturally derived as a smaller, more convenient unit for measuring smaller voltages.

Current use: Millivolts are used to measure small voltages in applications such as sensors, biomedical devices, thermocouples, and precision electronic circuits. It's a practical unit for measuring tiny changes in potential.

Volt

Definition: The volt (V) is the derived unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI). It is defined as the potential difference across a conductor when a current of one ampere dissipates one watt of power.

History/origin: The volt is named in honor of Italian physicist Alessandro Volta, inventor of the voltaic pile, the first chemical battery. The unit was established by the International Electrical Congress in 1881.

Current use: Volts are used universally to measure electrical potential difference in circuits, power systems, and electronic devices. It is a fundamental unit for specifying the voltage of power supplies, batteries, and electrical components.

Millivolt [mV] to Volt [V] Converter

To convert Millivolt to Volt, enter your value in the mV field above and the result in V will appear instantly. You can also use the conversion factor shown in the table on this page to calculate manually. The formula is always the same: multiply your mV value by the fixed conversion ratio to get the equivalent in V.

Our Millivolt to Volt converter uses standardized conversion factors defined by international scientific and metrological organizations. All calculations are performed with full floating-point precision. You can also choose how many decimal places to display in the result, so you get exactly the level of detail you need.

Yes, absolutely. Simply swap the source and destination units in the converter — select V as your input unit and mV as your output unit. The same precision and standardized conversion factor applies in both directions.

Converting between Millivolt and Volt comes up regularly in engineering, scientific research, construction, and everyday tasks that involve measurements from different unit systems. Our converter eliminates the risk of manual calculation errors and saves time whenever you need to switch between these two units.

Yes, the Millivolt to Volt converter is completely free. No account or registration is required, and there are no usage limits. It works on any device — smartphones, tablets, and desktop computers — directly in your browser.

Millivolt and Volt are both units used to measure the same physical quantity, but they belong to different measurement systems or represent different scales. The mathematical relationship between them is fixed and constant, which is what makes accurate conversion possible.
