Volts to millivolts
Type a value in V to get it in mV instantly.
100,000mV
That's 8.3× as high as a car battery, while US mains is 1.2× higher. Ohm’s law: volts = amps × ohms.
Convert the other way: mV to V
What it means
How high is that?
Mains figures are nominal: 230 V in Europe and 120 V in North America, both varying by a few percent.
The math
How to convert V to mV
To convert volts to millivolts, multiply by 1,000.
Example: 100 V × 1,000 = 100,000 mV.
In the other direction, 1 mV = 0.001 V.

About these units
Volts (V)
The SI unit of electrical potential. One volt drives one amp through one ohm.
Millivolts (mV)
A thousandth of a volt. Sensors, thermocouples and nerve signals work in millivolts.
