British Thermal Unit
A BTU is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.
In North America, 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 (BTU/h) is understood, though this is often confusingly abbreviated to just "BTU". In the UK and other parts of the world it is written BTU.
The unit MBTU was defined as one thousand BTU presumably from the Roman numeral system where "M" stands for one thousand (1,000).
Conversions
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)
Other conversions:
* In natural gas, by convention 1 MMBtu (1 million BTU, sometimes written "mmBTU") = 1.054615 GJ. Conversely, 1 gigajoule is equivalent to 26.8 m³ of natural gas at defined temperature and pressure.
* 1 MMBtu = 1,000 cubic feet (Mcf) natural gas
British Thermal Units. It's a measure of energy. It's the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.

basically in an air conditioner, there are 6,000 or 8,000 btu's etc..
you need to figure out the size of your room, and then that will determine how many btu's you need.. if you get too little btu's it may not get your room as cool as you like it, or it may take forever to get it cold.. so if you go on the internet they actually have btu calculators.. put in your room size..and it will tell you how many but's you will need!
BTU means nothing in an air conditioner.
It is a term used only for heat, therefore it is referring to the furnace.
The definitions offered above are good for heat.
