Square Foot Conversion Example

If your area is given in square meters and you want to know
square footage of it, you should type quantity of square meters in
the edit box labeled 'meter^{2}'. You will get square footage
of the area in the edit box labeled 'square foot'. On the other hand,
if you want to know how many square meters/centimeters/inches/yards are in an 1 square foot area,
type '1' in the edit box labeled 'square foot' and your answer will appear in the appriopriate
box.
