Millivolts to Volts converter (mV to V)
Convert Millivolts (mV) to Volts (V) with this free calculator. Type a value, press Convert, and the page applies the same factor shown in the formula below — no rounded shortcut, and nothing is stored on a server.
How to convert Millivolts to Volts
1 millivolt (mV) is equal to 0.001 volts (V).
V(V) = V(mV) × 0.001
Multiply the voltage in millivolts by 0.001:
Example: Convert 1,000 mV to V:
V(V) = 1,000 × 0.001 = 1 V

How this calculator works
The form on this page is a Millivolts-to-Volts converter. After you enter a number, JavaScript multiplies or rearranges it with the published conversion factor and writes the V result in the output box. The step-by-step panel repeats the arithmetic so you can copy it into homework or a spreadsheet.
