Kilovolt [kV] to Millivolt [mV] Converter

Quick Reference

1 Kilovolt (kV) = 1000000 Millivolt (mV)

1 Millivolt (mV) = 1.0000e-6 Kilovolt (kV)

How to Convert Kilovolt to Millivolt

1 kV = 1000000 mV
1 mV = 0.000001 kV

To convert Kilovolt to Millivolt, multiply the value by 1000000. To convert Millivolt back to Kilovolt, divide by 1000000.

Example: convert 10 kV to mV:
10 kV = 10 x 1000000 = 10000000 mV

↔ Convert Millivolt to Kilovolt

Kilovolt

Definition: A kilovolt (kV) is a unit of electric potential equal to one thousand (10Β³) volts. It is a multiple 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 kilovolt, as a decimal multiple of the volt, was derived as a larger unit for measuring high voltages.

Current use: Kilovolts are used to measure high voltages in power transmission lines, X-ray machines, and other high-voltage equipment. It is a convenient unit for expressing the magnitude of these large voltages.

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.
