I don't ever recall seeing it written that way, but yes, it's common for 
metric units.  I often see "sq. ft.", "sqft", and "cu. ft."  But I don't 
ever remember seeing ft^2 (superscript).

I actually wonder if that would confuse.
e.g.
"The area is about 100 feet square"
"100 square feet?"
"No, that would be 10,000 square feet."

I just wonder if writing it as "100 ft^2" could possibly be (mis)interpreted 
that way.
