Thermal British links

The British Thermal Links (Btu, BTU) is a unit of Anglo-Saxon energy which is defined by the quantity of Chaleur necessary to raise the temperature of a delivers English water of a degree Fahrenheit. It is often used to describe the quantity of heat being able to be released by a heating unit (Barbecue) or cooling (Climatisation).

The choice of the temperature to which the warming occurs leads to values slightly different (by approximately 0,5%) from the BTU:

A BTU is worth roughly:

252-253 cal (small Calorie S)
0,252-0,253 kcal (large calories, dietetic calories)
778-782 ft·lbf (foot-book-force)
1054-1060 Joule S

The quad (abbreviation of Quadrillion) is defined like being worth 10¹⁵ BTU, which is approximately 1,055×10¹⁸ joules, and the Therm is defined in the United States and in the European Union as being 100.000 BTU - but the United States uses BTU_59°F while the European Union uses BTU_IT.
