I remember learning the convertion formula for sizing up space for btus per ton and i could not find formula in any of my old notes, any one could help out?
There are too many variables with commercial to just use a "rule of thumb". You need to calculate the heat load. Computers, lighting, # of people , interior office, exterior office etc etc etc.

your totally correct thanx for info
the "rules of thumb" for residential is 700sq.ft/ton. for commercial it varies depending on the building use typical it runs around 350sq.ft/ton.
In AZ I consistently see designs that are 250 sq ft per ton. Airflows adjusted for windows and west facing walls. 8 years of engineering college and this is what you get.

one rule of thumb I've learned to never use is sq ft/ton .. its bs ...... especially in commercial
