Calorie : The calorie is a pre-SI metric unit of energy. Its symbol is cal, and first defined as a unit of heat by Nicolas Clément in 1824. The calorie is commonly used in the field of chemistry, and in many countries it is commonly used as a unit of food energy. There are two defined for the calorie, gram calorie (approximately equals 4.2 joules) and kilogram calorie (approximately equals 4.2 kilojoules).

MBTU : The unit MBtu is a measure unit of energy, defined as one thousand the British thermal unit (symbol: Btu). The "M" stands for one thousand, distinguishing with the SI mega (M) prefix, which stands for one million. In order to avoid confusion, many companies and engineers use MMBtu to represent one million Btu.
