No
No they are not the same. BTU is a unit of measure, square foot is another unit of measure. So BTU per square foot is refining the unit of measure further. Another example of your question would be: miles and miles per gallon, two different but related units of measure.
sorry
About 18000 BTUH. Rule of thumb is 400 sq ft / ton, 1 ton = 12000 BTUH.
Approximately 2.4 pounds per sq ft.
It depends on your enviornment. A 36,000 BTU unit will probably work just fine. 36,000 btu's would heat a 1,000 square foot room. or more.
It depends on the size of the sheet, and thickness. Usually particleboard is much heavier than plywood or osb. You can figure about 44 pounds per cubic foot.
12000 BTUs per 425-525 per sq ft.
12000 btu = 1 ton 1 ton per 400 sq ft 1200 / 400 = 3 3 times 12000 = 36000 btu
24,000 btu's
18,000-21,000 BTU's
36000 Btu
20 ft
Typically, you want to size your A/C at 12,000 btu's or 1 ton of cooling per 1,000 sq ft ,so at 3200 sq ft you would need a 3 ton or a 36,000 btu system. how ever if you live in a high humidity area than you adjust upward to 3.5 ton or a 42,000 btu . hope this helps good luck.
i get $3.72 per sq ft $3.72 per sq ft would be $55550.76 . The correct answer is 26.8 cents per sq ft.
At least 8000 btu
14000BTU
30' x 12'
700 to 1000
