I am sure the math whiz's will chime in with the correct math but I will attempt to answer. I measure the material by the inch to keep it as accurate as possible when trying to find the weight per square yard. One square yard is 1296".
(Width" X Length")/1296"=total Square Yards
Total Weight/Total Square Yards= Weight per square yard
