There are 12,000 Btu's per ton of air conditioning. The rule of thumb is 1 ton of A/C per 400 sq. ft

A rule of thumb is about 400 BTU per 100 square feet.
I used an 11,000 BTU window unit to cool the upstairs of our house - which I would guess was about 600 square feet and it did an adequate job. It kept it below the boiling point but not cold.

I don't know where those other people get their information, but I was taught in Tech School, and every HVAC company I have ever worked for use 600 ft2 as the rule of thumb for every ton of cooling. 1 ton being 12,000 btu's.
