What is a Kilojoule?
The kilojoule equals 1,000 Joules and is used on food nutrition labels in many countries — particularly in Europe, Australia, and Canada — as an alternative to calories. One kilocalorie (food Calorie) equals 4.184 kilojoules. A typical adult requires approximately 8,000–10,000 kJ of dietary energy per day. Running at moderate pace for one hour burns roughly 2,000–3,000 kJ.
What is a Gram calorie?
The gram calorie (small calorie, cal) is the heat required to raise the temperature of 1 gram of water by 1 °C, equal to exactly 4.184 Joules. It is used in chemistry and thermodynamics for heat calculations. The food 'Calorie' (capital C) printed on nutrition labels is actually a kilocalorie (kcal) — 1,000 times larger. One gram calorie is a very small amount of energy in everyday terms.
