Kilowatt-hours (kW·h) to Electronvolts (eV) Conversion
Kilowatt-hours
The kilowatt-hour (kW·h) is a unit of energy equal to exactly 3,600,000 joules (3.6 MJ), defined as the energy consumed by a one-kilowatt device operating for one hour. It is the standard unit on electricity bills worldwide. A typical European household consumes approximately 3,500 kWh per year. One kWh powers a 100-watt bulb for 10 hours, charges an electric vehicle by approximately 5–8 km of driving range, or powers the average laptop for about 10 hours.
Electronvolts
The electronvolt (eV) is a unit of energy equal to exactly 1.602176634 × 10⁻¹⁹ joules, defined as the kinetic energy gained by a single electron accelerated through a potential difference of one volt. It is the standard unit in particle physics, atomic physics, and solid-state physics. Visible light photons carry 1.8–3.1 eV of energy; X-ray photons carry 100 eV to 100 keV; the proton beams at CERN's LHC reach 6.5 teraelectronvolts (TeV).
