How to calculate AC costs?
Cost per Hour Formula (Most Popular)
For example, the average price of electricity in the U.S. was about $0.15 per kWh as of August 2023 according to the U.S.
Energy Information Administration.
Assuming a typical AC unit with a wattage of 1,500, the calculation would be (1,500W x $0.15) / 1,000 = $0.23 per hour.What size room will a 7.1 kW air conditioner cool?
For a room 10m2 to 20m2, a 2.6kW unit should cool the room; For a room 20m2 to 30m2, a 3.5kW unit should cool the room; For a room 30m2 to 45m2, a 5-6kW unit should cool the room; and.
For a room 45m2 to 65m2, a 7-8kW unit should cool the room.How do I calculate what size air conditioner I need?
Determining Air Conditioner Size
To calculate the size, simply multiply the length times the width of the room or area to be cooled.
Then, as a practical number, multiply that total times 25 BTU.
This allows ample cooling, whether it is a rainy, moist day or a hot, sunny, humid day.
