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).

Therm : The therm is a non-SI unit of heat energy equal to 1000,000 British thermal units (BTU). It is commonly used in measuring the natural gas in United Kingdom. One therm is equal to 1.055 056 × 108 joules.
