How it works

Joule and kilojoule are units of the International System. Calorie and kilocalorie are common in nutrition (the "Calorie" on food labels is actually a kilocalorie). Watt-hour and kilowatt-hour show up on electricity bills, and the BTU is used mainly to rate air conditioners. One kilocalorie equals 4.184 kilojoules; the other conversions between these units are detailed in the frequently asked questions below.
