How to Convert Volt to Millivolt
Voltage conversion is a metric prefix conversion around the volt, the SI derived unit for electric potential difference. Multiply the source voltage by the factor shown below to express the same electrical potential in the selected output unit.
1 volt
1000 millivolts
10 volts
10000 millivolts
100 volts
1e+5 millivolts
Voltage Formula Notes
The calculator converts through volts as the base voltage unit, then formats the result for the selected voltage scale. Microvolts and millivolts are common for sensors and signals, volts are common for circuits and batteries, and kilovolts through gigavolts are used for high-voltage and scientific references.
Volts to Millivolts Converter FAQ
Which voltage units are supported?
This tool supports microvolts, millivolts, volts, kilovolts, megavolts, and gigavolts.
How do I convert V to mV?
Multiply the V value by 1000 to get mV. The calculator performs the formula automatically and can also reverse the direction.
Is voltage the same as current or power?
No. Voltage is electric potential difference. Current is measured in amperes, and power is measured in watts. They are related in circuits, but they are different electrical quantities.
