1 mile = 5280 ft so 18000 ft = 3.409091 miles.
18000 sq ft = 0.41322 acres
According to the Energy Star chart, 12,000 BTUs will cool a room of 450 up to 550 square feet. I'd stay on the low end of that.
Around a million. plus or minus a few.

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.

The rule of thumb is 2-1/2 tons per 1000 square feet. It is not measured in BTU which is a heating term
The number of BTUs in a 6 ft baseboard heater would depend on the model and specifications of the heater. On average, a 6 ft baseboard heater can generate around 1,000-1,500 BTUs per linear foot, so a 6 ft baseboard heater may produce approximately 6,000-9,000 BTUs.
120 ft * 150 ft = 18000 sq ft = 0.413 acres (to 3 dp)
