What unit is commonly used on nutrition labels to express energy content?

Energy on nutrition labels is shown in kilojoules because kilojoules are the standard SI unit for energy used in labeling. This unit is a practical size for typical food energy values and keeps labeling consistent across foods and products. While some labels may also show calories (the kilocalorie, kcal), the commonly used value you’ll see on many nutrition panels is kilojoules. Joules would require huge numbers to represent foods, watt-hours aren’t relevant to food energy, and calories (kcal) are older and less commonly used as the primary label unit in many regions. For quick reference, 1 kcal equals about 4.184 kJ, so you can convert if needed.
