The electron volt (eV) is the energy gained by a single electron accelerating through a potential difference of one volt, equal to approximately 1.602 × 10⁻¹⁹ joules. It was formally adopted as a unit by the IEC in 1930.
Electron volts are the standard energy unit in atomic physics, particle physics, and semiconductor engineering. Chemical bond energies are a few eV; X-ray photons are kiloelectron volts (keV); particle accelerators measure GeV and TeV.
Interesting fact: The Large Hadron Collider accelerates protons to 6.8 TeV (6.8 × 10¹² eV). Visible light photons have energies of 1.8–3.1 eV. The rest mass energy of an electron is 511 keV.
The megawatt-hour (MWh) equals 1,000 kWh or 3.6 × 10⁹ joules. It is the standard unit for utility-scale electricity generation, large industrial consumers, and grid-level energy storage.
Power plants, wind farms, and solar installations are rated and billed in MWh. A 2 MW wind turbine generates about 6 MWh per day on average. Large data centers consume thousands of MWh per month.
Interesting fact: The Hoover Dam generates about 4,000 MWh per hour. A single nuclear power plant produces about 8,000 MWh per hour. World electricity consumption is approximately 25,000 TWh (25 billion MWh) per year.
Converting electron volt to megawatt-hour is common across energy, nutrition, engineering, and science. Different sectors use different energy units — joules in physics, kcal in nutrition, kWh in electricity, and BTU in HVAC — making accurate conversion essential for cross-disciplinary work and international comparisons.
