Every energy standard. One effortless converter. Mila's Energy Converter — part of the award-winning Mila's Tools family of converters — makes it easy to convert between every major energy unit. Whether you're working with food calories, electric bills, physics homework, or engineering specs, type one value and instantly see the result in every format. 13 SUPPORTED UNITS Metric/SI • joules (J) • kilojoules (kJ) • megajoules (MJ) • gigajoules (GJ) Thermal/Heat • calories (cal) • British thermal units (BTU) • kilocalories (kcal) • therms Electrical • watt-hours (Wh) • kilowatt-hours (kWh) Mechanical • foot-pounds (ft·lb) Scientific • electronvolts (eV) • ergs WHY IT MATTERS Energy is measured differently across industries: nutritionists use calories, electricians use kilowatt-hours, physicists use joules, and gas companies use therms.
