Acerca de Energy Converter
Physics homework uses joules, food labels use kilocalories, electricity bills use kilowatt-hours, and air-conditioner specs use BTU — four dialects of the same quantity. This converter switches between them all from one input, with the food-label convention handled correctly: one "Calorie" on a label is one kilocalorie, 4184 joules. Also includes watt-hours for battery capacity comparisons.
