One calorie (cal) is exactly equivalent to 4.19 Joules (J). What do we use calories for? The energy that food provide us is calculated in kilocalories (kcal) and kilojoules (kJ). Mainly, we use calories to: To calculate energy needs:“this boy must eat 2,000 kcal a day.” To ...
This lesson explores the concepts of energy, work, and power. It defines them and discusses their units of measurement. With the focus on energy, the lesson presents different units, such as: J, BTU, Therm, Kcal, cal, and KWh. It also provides information about how to perform a conversio...
the energy required depends slightly on the starting temperature of the water. The SI definition of calorie is now 1 calorie equals 4.184 joules. In specific terms, the energy would typically be measured as calories/gram (cal/g), kilocalories/kg (kcal/kg), or kilocalories per gram (kcal/...
The unit of heat is joule (J) in SI unit system and calorie is used in BTU system of units. For heat transferred, watt is the standard unit.
