Usually, depending on a few other factors, you need 20 to 22 btu per square foot. Higher ceilings and more windows require more.
12000 btu should cover about 550 to 600 square feet of space.

There are at least 5 different definitions for slightly different BTUs. One of them says that 1 kWh = 3412.14 BTUs. Let's use that one. 1 kWh = 3412.14 BTUs 12 kWh = 40,945.68 BTUs

To calculate the BTUs needed to cool a room, multiply the square footage of the room by 20 (which is the recommended cooling capacity in BTUs per square foot). In this case, for a 20x12 room (240 square feet), you would need approximately 4,800 BTUs to effectively cool the space.
Tonnage is 2 1/2 tons. The 30 indicates the amount of BTUs in hundreds(30hundreds or 3000). 12000 BTUs=1ton, 2400=2tons ,1/2 ton=600 BTUs, thus 12000+12000+6000=30000 or 30hundreds BTUs=2 1/2 tons.
12000 BTUs per 425-525 per sq ft.
1 ton = 12000 BTUs
Air conditioner BTUs are recommended based on the square footage of a room. A room that is 20'x28'x15' high has a square footage of 560, as the height is not usually factored in. A room that is 560 square feet should have an AC with at least 18,000 BTUs. Because of your high ceiling, though, consider one with at least 20,000.

To determine the appropriate air conditioner size for a room, you need to calculate the required capacity based on the room's square footage. The general rule is to have 20 BTUs (British Thermal Units) per square foot of space. To calculate the required capacity, multiply the square footage of the room by 20. For example, a room that is 300 square feet would need an air conditioner with a capacity of 6,000 BTUs.
4800 BTUs will 150 square feet.
To convert a watt to BTUs, the factor is 1 kilowatt of power = 3412.1416 BTU/hr 3.412 BTUs equal a watt. 1200 watt = 4094.4 BTUS you will need to remove about 4100 BTU/hr
It will take 300000 btus at 12000 a ton and a ton of air will be 400 sq feet so. 10000 sq ft divided by 400 is 25 tons of air then multiply 25 times 12000 btus and you get 300000
For a 600 square foot room, you would typically need around 18,000 BTUs of cooling capacity to effectively cool the space. This estimate is based on the general guideline of 30 BTUs per square foot for cooling larger rooms.
To calculate the BTU needed to heat a house, first determine the square footage of the space to be heated. Next, multiply the square footage by a BTU factor that accounts for insulation quality, climate, and ceiling height, usually around 20 BTUs per square foot for average conditions. Finally, adjust for specific factors such as windows, doors, and the number of occupants, using a more detailed heat loss calculation if necessary. This will give you an estimate of the total BTUs required for effective heating.
