🔋 Energy Converter
Enter an energy value in any unit and see it converted to every other unit at once — Joules, calories, food Calories, watt-hours, kWh, BTU and foot-pounds.
"Calorie" here means the small thermochemical calorie (4.184 J). The "Calorie" used on nutrition labels is actually a kilocalorie (1000 small calories, 4184 J) — that's the "Kilocalorie / food Calorie" row below.
