Volt [V] to Millivolt [mV] Converter

Quick Reference

1 Volt (V) = 1000 Millivolt (mV)

1 Millivolt (mV) = 0.001 Volt (V)

How to Convert Volt to Millivolt

1 V = 1000 mV
1 mV = 0.001 V

To convert Volt to Millivolt, multiply the value by 1000. To convert Millivolt back to Volt, divide by 1000.

Example: convert 10 V to mV:
10 V = 10 x 1000 = 10000 mV

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

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 [V] to Millivolt [mV] Converter

What is 1 V in mV?
1 Volt (V) equals 1,000 mV, and 1 mV equals 0.001 V.
How do I convert Volt to Millivolt?
Multiply by 1,000: 10 V × 1,000 = 10,000 mV. The converter above does it for any value, with the precision you choose.
What is 100 V in mV?
100 V = 100,000 mV. Common amounts are listed on this page, each with its own step-by-step page.
Is a Volt bigger than a Millivolt?
Yes. 1 V = 1,000 mV, so the same quantity becomes a larger number when written in mV.
