BTU's (British Thermal Units) and two dimensional area are not compatible measurements.
20 btu per square foot
usually 20 btu's per square foot so......12000 btu's should do fine

A 12,000 BTU heater is needed for a 1,400 square foot area. BTU or British Thermal Unit is a unit of measure commonly used for heating and cooling.
Many factors figure in other than square footage. Such as the height of the ceiling and number of windows. But, for most houses, 20 to 22 btu per square foot will do. 40,000 to 45,000 btu should do.
The ideal mini split BTU per square foot for efficient cooling in a residential space is around 20-30 BTUs per square foot.
To determine the BTU requirement for a 12 x 12 room with a 12-foot ceiling, you can start with a basic calculation of 20 BTU per square foot. For a 144 square foot room, this equates to approximately 2,880 BTU. However, considering the high ceiling and other factors such as insulation, sun exposure, and occupancy, you may want to increase the capacity to around 3,500 to 4,000 BTU for optimal cooling.
An 800 square foot area need a 15,000 BTU air conditioner to properly cool. Properly sizes the AC unit ensures that the unit will not be overworked.
