Energy converters

Energy converters cover a uniquely wide range: a chemical bond is a few eV, a heartbeat is about 1 J, an espresso machine uses around 100 kJ of electricity per shot, and a US household consumes roughly 30 kWh per day. All factors here are exact: 1 cal = 4.184 J (thermochemical), 1 BTU (IT) = 1055.05585262 J, 1 kWh = 3,600,000 J, 1 eV = 1.602176634 × 10⁻¹⁹ J (2019 SI).
