Explanation

Both Calorie and Joule are valid units for measuring heat energy. Calorie (cal) is the traditional unit, specifically the amount of heat needed to raise 1 gram of water by 1°C. Joule (J) is the SI unit of energy, including heat energy. The conversion is approximately 1 calorie = 4.184 joules. Both are widely used in different scientific contexts.
