If you are looking to install or replace an air-conditioner and would like to know what the size of air-conditioner you need, you can follow the following steps:
1) Obtain the dimensions of your room in feet- i.e. length and width
2) Calculate the area of the room in square feet-i.e. by multiplying length and width you have calculated in 1).
3) With the area calculated in 2), multiply this result by 65: this will give you the cooling capacity of the aircon in BTU/hr.
4) As 1 electrical kW=3,414.43 BTU/hr, and 1 HorsePower (HP) = 2,546.143 BTU/hr, you can further divide/multiply your answer in 3) to derive the subsequent cooling capacity in HP or kW.
In our Singapore mandarin parlance, we call air-conditioner "ren qi" which I think is not correct as "ren qi" means cold air. The more accurate name should be "kong tiao" which describes the conditioning of air as used in China/Taiwan.
