Multiply your measurement in square feet by (1 yd2/(9 ft2)).
Example
12 ft2 = 12 ft2*(1 yd2/(9 ft2)) = 12/9 yd2 = 1 1/3 yd2
_____
Any units conversion is accomplished by multiplying by an appropriately chosen form of 1. Here, we use 1 = ((1 yd)/(3 ft))2 = (1 yd2/(9 ft2))
Example
12 ft2 = 12 ft2*(1 yd2/(9 ft2)) = 12/9 yd2 = 1 1/3 yd2
