Re: Converting feet and inches into square yard
There are 12 inches in a foot
there are 3 feet to a yard
there are 36 inches in a yard
there are 36 x 36 = 1296 square inches in a square yard
there are 3 x 3 feet = 9 square feet in a square yard
if you are working with feet and inches, it is best to convert the feet to inches until your final calculations, it's just easier that way.
I usually will work out a problem both ways as a way to double check my work. It's just that in the working world mistakes can cost a lot of money.Last edited by Sandra; 11122007, 08:38 AM. Reason: to add comment about working problems out both ways to double check results

Re: Converting feet and inches into square yard
I work for a concrete and asphalt company and here at work we calculate length x width = square feet.
We then divide by 9 to calculate the square yards.
So, for example:
29'5" x 20' = 590 square feet
590sf / 9 = 65.56 square yards.
To convert square yards to cubic yards (in case you need to know this):
Take your total amount of square yards (65.56sy) x 9 (sq ft in a yard) x depth (4" sidewalk or 6" driveway or 8" street, etc) then divide by 324 = cubic yards
So, 65.56 sy x 9 x 6" (driveway) = 16.39 cubic yards of concrete needed.

Re: Converting feet and inches into square yard
By using Sandra's info above, you now know that there are 9 sq ft in 1 sq yd.
So, now all you have to do is just divide your total amount of square feet by 9 to get your answer of total square yards.
For example:
75'6" / 9 = 8.4 sq yds
12 feet / 9 = 1.33 sq yds
47' 3 " / 9 = 5.25 sq yds
100 feet / = 11.11 sq yds

One of my favorite math teachers said that math isn't learned from a book but actually from the point of a sharp pencil.
You will find that you learn more just by playing with the numbers. If we give you all the answers it won't help next time you have to do a similar problem.

So 12 ft 5 in = 12/3 + 5/36 yd = 4.1389 yd
8 ft 8 in = 8/3 + 8/36 yd = 2.8889 yd
The area is the product, 11.96 yd²
