Convert Megawatt-Hours to Electronvolts

Convert Megawatt-Hours (MWh) to Electronvolts (eV) instantly and accurately.

Conversion Formula

eV = MWh × 2.246943267e+28

About Megawatt-Hours

A megawatt-hour (MWh) is the energy from 1 MW for one hour - exactly 3.6 GJ. It is the standard unit for wholesale electricity trading. Power purchase agreements (PPAs) specify capacity and price in $/MWh or €/MWh. A 5 MW wind turbine at full capacity generates 5 MWh/h. Primary aluminium smelting consumes 13-15 MWh per tonne. The Moss Landing battery (California) stores 3,287 MWh. The daily output of a 1 GW nuclear plant at 90% capacity factor is ~21,600 MWh. 1 MWh = 3.6 GJ = 3,412,141 BTU = 1,000 kWh.

About Electronvolts

An electronvolt (eV) is the kinetic energy gained by one electron accelerated through 1 volt - exactly 1.602176634 × 10⁻¹⁹ J (fixed by the 2019 SI revision). It is the natural energy unit of atomic and particle physics: visible light photons carry 1.7-3.1 eV; hydrogen ionisation requires 13.6 eV; X-ray photons span 100 eV-100 keV; protons at the LHC reach 6.5 TeV. Rest masses use eV/c²: electron 0.511 MeV, proton 938.3 MeV, Higgs boson 125 GeV. Nuclear binding energy peaks at ~8 MeV/nucleon for iron-56. 1 eV = 1.602176634 × 10⁻¹⁹ J.
