Conversion Formula
kV = V × 0.001
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.
About Kilovolts
The kilovolt (kV) equals 10³ V, used in high-voltage power supplies, X-ray machines, and electricity distribution. Dental and medical X-ray tubes operate at 60-120 kV; CRT television picture tubes required 20-30 kV for the final anode; distribution transformers step down from transmission lines at 11-33 kV to the local grid. Tesla coils generate sparks at tens to hundreds of kilovolts. 1 kV = 10³ V = 10⁻³ MV.
