Energy Converter
Convert between Joules, Calories, kWh, BTUs, and eV.
Energy Converter
Examples:
Conversion factor
1 Kilowatt-hour (kWh) = 3.6 Megajoule (MJ)
Formula: joules = value × 3600000; result = joules ÷ 1000000
Bulk conversion
One value per line. Add a unit per line (500 kcal, 2 kWh) or leave it off to use the From unit. Output is in Megajoule (MJ).
