Energy Converter
Convert between common energy units by entering a value and selecting the units you want to convert from and to.
To convert Kilocalories to Kilojoules, 1 Kilocalories is equal to 4.184 Kilojoules.
Formula
Energy conversions use fixed relationships between units. For example, 1 kilocalorie (kcal) equals 4,184 joules (J), 1 kilowatt-hour (kWh) equals 3,600,000 joules (J), and 1 BTU is approximately 1,055.06 joules (J).

How It Works
Select an energy unit for the input and another unit for the result. Enter a value, and the converter calculates the equivalent energy using standard conversion factors between joules (J), kilojoules (kJ), calories (cal), kilocalories (kcal), watt-hours (Wh), kilowatt-hours (kWh), and BTU.
Example
1 kilocalorie equals 4.184 kilojoules. 1 kilowatt-hour equals 1,000 watt-hours. 1 BTU is approximately 1,055.06 joules.
