Then as a practical number multiply that total times 25 btu.
Here we are calculating how much amount of heat btu s we need to absorb from a room and then select the right size of ac.
This air conditioner calculator can only provide you the recommended output power of the ac in british thermal units per hour btu.
What if i use too low of a btu for the room size.
Air conditioner btu chart.
Other factors in determining the btu size would be the room s purpose.
That means 12x15 180.
