How do you measure BTU output?
Calculate the wattage of the device by multiplying the volts by the amps. For example, if the device has a voltage of 160 volts and a current of 2 amps, its wattage would be 320 watts (160 times 2). Divide the result by 3.413 — a constant figure — to determine the BTUs per hour.

How do I know the BTU of my air conditioner?
Find the model number. Within this string of letters and numerals, you should find an even, two-digit number. The possibilities on residential units range from 18 to 60. Divide the number by 12 (which represents 12,000 Btu/hr, or one ton of cooling capacity) to get your AC unit’s tonnage.
What is BTU meter?
BTU meters measure the energy content of liquid flow in British thermal units (BTU), a basic measure of thermal energy. BTU meters are used in chilled water systems for both commercial and industrial and office buildings. These meters are used to bill users for energy usage.
How do I calculate the size of my aircon?
Using a formula to calculate your air conditioning needs If your ceiling is 2.4m high, you will need to multiply the daytime living area (m²) by 150 (watts) If your ceiling is 2.7m high, you will need to multiply the daytime living area (m²) by 160 (watts).
What size aircon do I need?
As a general rule we advise you to buy an Air Conditioner with a minimum 7000BTUs as this is the minimum required to call a small room (18sq/m) on a hot day. Medium rooms (24sq/m) need around 10,000BTUs and larger rooms and office spaces (36sq/m) require around 15000BTUs.
How many sq ft does a 15000 BTU AC cool?
Those in the 12,000- to 15,000-Btu range cost from $450 to $600, while large units go up to $1,200. Air conditioners rated at 15,000 Btu should be enough to cool most rooms up to about 875 sq. ft.
How do you size a window air conditioner?
As a rule of thumb, an air conditioner needs 20 Btu for each square foot of living space. But other considerations, such as the ceiling height and the size of your windows and doorways, might call for more cooling power. To measure your room, multiply the length by the width.
How many BTU is 600 square feet?
Answer: Using the EPA’s 20 BTU per sq ft rule of thumb, the room size of 12,000 BTU air conditioners is 600 sq ft. Equally, 1 ton AC room size is about 600 sq ft. Again, when narrowing down your choice of an air conditioner, knowing how big an area you need to cool is your best friend.
How do I measure my aircon for a room?
Calculate 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. Let’s say the room is 12 feet wide by 15 feet long.
How do you calculate an air conditioner for a room?
To calculate a room’s area in square feet, simply multiply its length by its width. For instance, if the room is a rectangular 10 feet by 20 feet, the area would be 200 square feet. If the room is a perfectly-square 20 feet by 20 feet, the total area would be 400 square feet.
How do you size a commercial air conditioner?
Estimating Your Ideal A/C Size Calculate the square footage of the space (building or group of rooms) you want to cool. Divide the space’s square footage by 500. Multiply the number from Step 2 and by 12,000. Add 380 Btu for each person who works in the space all day. For each window in the space, add 1,000 Btu.
How many BTUs is 1hp aircon?
When choosing an air conditioner, usually a 1 HP (horse power) equipment is able to remove 9,000 BTU/hr of heat. With better technology, some machines are able to remove 10,000 BTU/hr of heat with the same capacity. The higher the listed BTU/hr, the greater the cooling capacity.
What size room will a 12000 BTU air conditioner cool?
12,000 BTUs will cover 400 sq. ft. (3,200 cubic feet) 13,000 BTUs will cover 450 sq.
Can window AC cool entire house?
Window air conditioners are designed to cool only a single room. It is very difficult for such AC to cool an entire house. At most you can cool two adjacently connected tiny rooms with a single window AC, but there will be uneven cooling.
What size room will a 12000 BTU cool?
A 12000 Btu unit will effectively cool a room with a floor space of 500 to 600 square feet.
How many sq ft will 18000 BTU cool?
BTU Sizing Chart for Mini Split Systems Area To Be Cooled Capacity Needed (BTUs Per Hour) 450 to 550 square feet 12,000 BTUs 550 to 700 square feet 14,000 BTUs 700 to 1,000 square feet 18,000 BTUs 1,000 to 1,200 square feet 21,000 BTUs.
How do you measure a window?
Measure the height from the head of the window (top fixed-frame piece) to the windowsill (bottom fixed-frame piece) As with the width, take three measurements: down the left side, right side and the middle. Record the shortest measurement — this ensures that the new window will fit.
