Convert Volts to Millivolts
Convert volts to millivolts by entering a value below.
How to Convert Volts to Millivolts
The volt and millivolt are both units of voltage. By definition, 1 millivolt equals exactly 1000000 volts. This means to convert volts to millivolts, you divide by 1000000.
Formula
Step-by-Step Example
Convert 5 V to millivolts:
We need to convert volts to millivolts
Since 1 mV = 1000000 V, divide by 1000000
5 ÷ 1000000 = 5e-6
5 V = 5e-6 mV

About These Units
Volt (V)
The volt (V) is the SI unit of electric potential, voltage, and electromotive force (EMF). One volt drives one ampere through one ohm (V = I × R). Named after Alessandro Volta. Common voltages: USB 5V, car battery 12V, US outlet 120V, EU outlet 230V, EV battery 400-800V. Formula: V = W/A (watts per ampere).
Millivolt (mV)
A millivolt (mV) equals 0.001 volts. Common for sensor outputs: thermocouple 0-50 mV, strain gauge 2-3 mV/V, audio line level 200-775 mV RMS. ECG signals: 1-10 mV. Solar cell open-circuit: 500-700 mV per cell. Critical for instrumentation and signal processing.
