Air conditioner btu chart.
Btu per room size.
A btu is the heat needed to raise the temperature of one pound of water by one degree fahrenheit.
These btu calculations are based on a standard room with 8 foot ceilings two windows and one door.
This btu calculator will determine what hearth product size is required with only a few steps and information such as square footage sq ft.
This air conditioner room size calculator also known as an ac btu calculator will help you decide what size of air conditioner to buy so you can be efficiently cool or heat your room of course the choice of brand and air conditioner type still depends on you.
To figure out what size air conditioner you require you first need to determine the amount of btus you require.
Btu is often used as a point of reference for comparing different fuels.
This air conditioner calculator can only provide you the recommended output power of the ac in british thermal units per hour btu.
The chart below is a great starting point for sizing your ac.
Then add the square footage for each room together.
To cool a bigger or busier room you ll want to step up to a midsized air conditioner rated at 7 000 to 8 500 btu.
Here are three top picks.
If the room has more windows doors or higher ceilings adjust the btus upward.
Simply measure the length and width of a room and figure the square footage.
A british thermal unit or btu is a unit of measurement of energy.
Calculate how many btus you need to heat a room or even a house with a wood burning pellet or gas fireplace insert or stove.
This is done by calculating your square footage.
1 btu is the equivalent of 1 055 joules or 293 watts.
1 btu 1 055 joules 252 calories 0 293 watt hour or the energy released by burning one match.
Other factors in determining the btu size would be the room s purpose.
For air conditioners there is a btu to room sizing rule of thumb.
The larger the space the more btus are needed.
1 btu is the energy needed to heat 1 pound of water by 1 fahrenheit.
Btus stand for british thermal units and refer to the amount of energy your air conditioner is using per hour.
Multiply the two together to get 150 square foot room.
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.
We often refer to the british thermal unit as a btu but the rating is actually the btus per hour or btu h.
To calculate btu per square foot start by measuring the square footage of each room you want to heat or cool.
It is approximately the energy needed to heat one pound of water by 1 degree fahrenheit.
Break up each room into as many squares and rectangles as you need to be.
Let s say it is a 10 foot by 15 foot room.
This can provide a rough estimate of the mini split btu per square foot you need to efficiently service the room.
