3600in² to square feet

square in = in² = in·in
square ft = ft² = ft·ft

12in = 1ft

%283600in%5E2%29%2F1 = %283600in%2Ain%29%2F1×%281ft%29%2F%2812in%29×%281ft%29%2F%2812in%29

Cancel the inches:

%283600cross%28in%29%2Across%28in%29%29%2F1×%281ft%29%2F%2812cross%28in%29%29×%281ft%29%2F%2812cross%28in%29%29

End up with
 
%283600%29%2F1×%281ft%29%2F%2812%29×%281ft%29%2F%2812%29

%283600%2Aft%2Aft%29%2F%2812%2A12%29

3500%2F144ft·ft

25ft²
