Convert Millivolts to Volts
Convert Millivolts (mV) to Volts (V) instantly and accurately.
Conversion Formula
V = mV × 0.001
About Millivolts
The millivolt (mV) equals 10⁻³ V, the everyday scale of biomedical and electrochemical measurements. ECG R-wave peaks are 0.5-3 mV; a silicon p-n junction has a forward voltage of about 600 mV; pH electrodes produce roughly 59.2 mV per pH unit (Nernst equation at 25 °C); lithium-ion cells have an end-of-discharge cutoff at 2 700-3 000 mV. 1 mV = 10⁻³ V = 10³ µV.
About Volts
The volt (V) is the SI derived unit of electric potential, defined as 1 joule per coulomb (1 J/C = 1 W/A = 1 kg·m²·A⁻¹·s⁻³). Named after Alessandro Volta who built the first electrochemical battery in 1800. Common benchmarks: a fresh AA alkaline cell is 1.5 V; USB 2.0 supplies 5 V; a car lead-acid battery is 12 V; household electricity in Europe is 230 V RMS. The volt is reproduced internationally via the Josephson voltage standard.
