One calorie is the amount of heat required to raise the temperature of one gram of water by one degree Celsius. As such calorie is a very small unit hence larger unit Kilocalories or Kcal is more commonly used. 1Kcal = 1000 cal. 2) SI unit system: Joule: This system is most commonly used now.
In the metric system, heat is measured in units of calories, which are defined as the amount of heat required to raise the temperature of one gram of water from 14.5oC to 15.5oC. In the SI system, the unit of heat is the joule. Heat Capacity. The heat capacity of a substance is the amount of heat required to raise the temperature of a defined amount of pure substances by one degree (Celsius or Kelvin). The calorie was defined so that the heat capacity of water was equal to one.
