what is a BTU Ratings in a grill? It is for a math project.?

Answer 1

BTU’s – British Thermal Units
BTU stands for British Thermal Unit, which is a measurement of heat output. So how should BTU’s factor into your purchase decision? Although the number of BTU’s should increase as the main cooking surface increases, it is important to know that more BTU's do not necessarily mean a better performing grill. Our research indicates that having 100 BTU’s per square inch of primary cooking surface is ideal for optimum performance in a Fiesta gas barbecue grill. This BTU range will allow you to heat your grill high enough to sear a steak, and then lower the BTU output to maintain the ideal cooking temperature.

The British thermal unit (BTU or Btu) is a unit of energy used in North America. It is also still occasionally encountered in the United Kingdom, in the context of older heating and cooling systems. In most other areas, it has been replaced by the SI unit of energy, the joule (J).

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".

Answer 2

BTU stands for British Thermal Units. A very simple way to explain this is it is a way to measure heat. example- if your grill puts out 10,000 BTU it would heat the food faster than an 8,000 BTU grill, but to achieve this you more than likely would use more fuel or burn the fuel more efficiently. If you just need a rating off a grill it will be listed on the grill.

Answer 3

A British Thermal Unit or BTU is a convenient expression of heat energy. 1 BTU is the amount of energy required to raise 1 pound of water 1 ºF.

Answer 4

The wikipedia page on BTU shows how to convert to/from kilowatts.

2nd link gives BTUs for a typical grill.
