Then, we also need to consider the location of the room and its type (whether it's a bedroom or a kitchen, etc.). There are 12,000 btu's per ton. Determining your btus air conditioners are sized by the number of btus they put out.
To get power, we have to use some time unit as in 'this or that air conditioner can produce 10,000 btu of power per hour'.
1 watt is approximately 3.412 btu per hour. So a model with a higher btu rating has more cooling power. If the room has more windows, doors or higher ceilings, adjust the btus upward. Just like with heaters, the higher the btu rating of an air conditioner, the. Btu ratings specify how many btus the air conditioner moves. Square feet and btu output. Btu is one of the most important factors to consider when looking for the ideal sized cooling or heating system for a house. About 150 to 250 square feet need 6,000 btus, 300 to 350 square feet need 8,000 btus, 1,000 to 1,200 square feet need 21,000 btus, and 1,500 to 2,000 square feet need 30,000 btus. In some cases, a portable air conditioner is referred to as a 1 ton, 3 ton, or 5 ton air conditioner. Btu is a measure of energy, not power.

Remember, too little is never enough and too much of a good thing can be bad. To find the average power consumption, divide the unit's power in btus per hour by the seer rating. Using the sizing chart to calculate the appropriate btu rating needed to cool that area of the home, it's an easy selection choice from there. The rating is actually btu/hour, or the number of btus the air conditioner removes from the space in one hour. A btu, or british thermal unit, is the amount of energy needed to raise 1 pound of water by 1 degree fahrenheit while at sea level. As a rule of thumb:
If the room has more windows, doors or higher ceilings, adjust the btus upward.
The simplest btu calculation formula for an air conditioner looks like this: Write down the maximum wattage it uses. The rule of thumb is 1 ton equals approximately 12,000 btu. If the room has more windows, doors or higher ceilings, adjust the btus upward. We need to adjust the recommended btu per hour capacity of the air conditioner by about 600 btu/hr for each additional person. Btu is one of the most important factors to consider when looking for the ideal sized cooling or heating system for a house. A btu, or british thermal unit, is the amount of energy needed to raise 1 pound of water by 1 degree fahrenheit while at sea level.
