How the Energy Converter Works
This energy conversion tool converts all energy values to joules internally and then transforms them into the selected target unit using scientific formulas.
Supported Energy Units
- Joule (J)
- Kilojoule (kJ)
- Calorie (cal)
- Kilocalorie (kcal)
- Kilowatt-hour (kWh)
- British Thermal Unit (BTU)
- Watt-hour (Wh)
Common Energy Conversions
- J → kJ = J ÷ 1000
- J → cal = J ÷ 4.184
- kWh → J = kWh × 3,600,000
- BTU → J = BTU × 1055.06
