Millivolts to Volts Converter

Convert millivolts (mV) to volts (V), with the formula, a conversion table and exact factors.

Change the values and press Calculate to work out your own figures.

Enter a voltage, choose its unit and the unit you want. The answer is exact until it is shown, and the same value appears in every other unit.

A number, fraction (3/8), mixed number (1 1/2), scientific notation (2.5e6) or a simple sum such as 2*3.
The unit you want the answer in. Swap exchanges the two units.

How to convert millivolts to volts

1 mV = 0.001 V, so multiply by 0.001 to go from millivolts to volts. Going the other way, 1 V = 1,000 mV.

V = mV × 0.001
mV = V × 1,000

Worked example:

1 mV = 0.001 V
5 × 0.001 = 0.005 V
