In the United States, the term "BTU" is used to describe the heat value (energy content) of fuels, and also to describe the power of heating and cooling systems, such as furnaces, stoves, barbecue grills, and air conditioners. When used as a unit of power, BTU per hour is understood, though this is often confusingly abbreviated to just "BTU".
One BTU is approximately:
1,054-1,060 joules
252–253 cal (calories, small)
0.252–0.253 kcal (kilocalories)
778–782 ft·lbf (foot-pounds-force)
