Tag: Kilojoule vs calorie

While both kilojoules and calories measure energy, a recent study from Healthline shows that one dietary calorie is equivalent to 4.184 kilojoules. They are different units for the same physical quantity, often causing confusion for those tracking their dietary intake.

The simple answer is no, they are not the same unit, but rather two different ways of measuring the same thing: energy.
