About Electronvolt (eV)
A unit of energy equal to the energy gained by an electron accelerating through a one-volt electric field (exactly 1.602176634 × 10⁻¹⁹ joules). The electronvolt is the working unit of atomic, molecular, and particle physics: chemical bonds are a few eV; X-rays carry keV (thousands of eV); nuclear reactions release MeV (millions); particle colliders operate at GeV-TeV (billions-trillions). Almost every modern particle-physics paper reports energies in eV.
About British Thermal Unit (BTU)
An imperial unit of heat energy, defined as the amount of heat required to raise one pound of water by 1°F (about 1,055 joules). BTUs are the dominant unit in US HVAC and heating/cooling: air conditioner capacity (a 12,000 BTU/h unit is a "1-ton AC"), gas furnace output, and natural gas heating content. "MMBTU" (million BTU) is the US energy wholesale unit for natural gas and industrial fuel contracts.
