Calculating your air conditioning requirements
Heat Load
The amount of heat generated is known as the heat gain or heat load. Heat is measured in either British Thermal Units (BTU) or Kilowatts (KW). 1KW is equivalent to 3412BTUs.
The heat load depends on a number of factors, by taking into account those that apply in your circumstances and adding them together a reasonably accurate measure of the total heat can be calculated.
Factors include:
Floor Area of Room
The amount of cooling required depends on the area of the room. To calculate the area in square metres:
Room Area BTU = Length (m) x Width (m) x 337
Window Size and Position
If, your room has no windows, you can ignore this part of the calculation. If, however there are windows you need to take the size and orientation into account.
South Window BTU = South Facing window Length (m) x Width (m) x 870
North Window BTU = North Facing windows Length (m) x Width (m) x 165
If there are no blinds on the windows multiply the result(s) by 1.5.
Add together all the BTUs for the windows.
Windows BTU = South Window(s) BTU + North Window(s) BTU
Occupants
You will have to take that into account people who normally working in the space. The heat output is around 400 BTU per person.
Total Occupant BTU = Number of occupants x 400
Equipment
Clearly most heat in a room is generated by the equipment. This is trickier to calculate that you might think. The wattage on equipment is the maximum power consumption rating, the actual power consumed may be less. However it is probably safer to overestimate the wattage than underestimate it.
Equipment BTU = Total wattage for all equipment x 3.5
Lighting
Take the total wattage of the lighting and multiply by 4.25.
Lighting BTU = Total wattage for all lighting x 4.25
Total Cooling Required
Add all the BTUs together.
Total Heat Load = Room Area BTU + Windows BTU + Total Occupant BTU + Equipment BTU + Lighting BTU
This is the amount of cooling required so you need one or more air conditioning units to handle that amount of heat.
This is a two-step question. First, to convert volt-amps into watts, multiply by the power factor. For a heating element like a convector or kettle the power factor is 1, but for a motor it might be 0.7. In the absence of information a power factor of 0.8 can be assumed. Watts are a measure of power and the equivalent imperial measure is BTU per second or BTU per hour. Alternatively a BTU is a measure of energy and the metric equivalent is watt-seconds or watt-hours. A BTU is 1055 watt-seconds (also known as joules). A kilowatt-hour is equivalent to 3412 BTU.
Btu is a unit of heat.Horse power is the measurement of power.Now,in order to correlate BTU and HP,We can say BTU*TIME(Hr)*3.931e-4=Horsepower. Hence 48000 BTU Hr is 18.8 Horsepower
0.29308323563892147 watts per btu there for 5200 btu = 1524.0328253223915 watts 1 watt=3.412Btu/hr 1 Btu=the amount of energy needed to heat 1 Lb of water 1 degree. A gallon of water weighs aprox. 8 Lbs.
About 90 percent of an incandescent bulb's energy is turned into heat; one watt is 3.41 btu/hr, so 10 watts would be about 3 btu per hour.

1 therm unit equals 100000 btu's
Temperature IS BTU, BTU is: British Thermal Unit, I believe the formula is this: How long it takes one pound of ice to melt at room temperature with no air moving around it, Room temp. being 73 degree F. I think? maybe 72? anyway the time is equal to one BTU. Maybe someone who knows the formula exactly can edit this.
it is the by the undr
5000 BTU's should work for a room that size.
About 8,000 BTU
anywhere from 5,000 btu - 6,500 btu
Joule, calorie, BTU (British Thermal Unit)
At least 8000 btu
Heptane has the chemical formula of C7H16. It has a BTU rating of 19,163 BTU per pound and a rating of 4,465.8 kilojoules per mole.
usually 20 btu's per square foot so......12000 btu's should do fine
To convert CFH to BTU, you need to use the formula 1 CFH which is equivalent to 1000 BTUs.
1 BTU needed to raise or lower 1degree F of 1 lb water
