Voltage Converter

Convert voltage between volt (V), millivolt (mV), and kilovolt (kV). Whether you are working with sensor signals in millivolts or high-voltage transmission lines in kilovolts, this tool provides instant and accurate conversions.

Common Voltage Scales

Millivolts are used for small sensor outputs and biological signals. Volts are the SI unit for everyday electronics and household power. Kilovolts are used in power distribution, industrial equipment, and high-voltage testing.

Frequently Asked Questions

How many millivolts are in one volt?

One volt equals 1000 millivolts. To convert volts to millivolts, multiply by 1000. To convert millivolts to volts, divide by 1000.

What is a kilovolt used for?

Kilovolts (kV) are used in electrical transmission lines, substations, and large industrial motors. Standard distribution voltages include 11 kV, 33 kV, and 132 kV.

Is household voltage 110V or 120V?

North American household outlets typically provide 120V nominal. Some regions use 110V or 115V as approximate values for the same standard.

How do I convert mV to kV?

Divide millivolts by 1,000,000 to get kilovolts. For example, 5,000,000 mV = 5 kV. This tool handles the conversion automatically.
