Look being one of the main reasons tile and carpet places like to sell things by the square yard.No because it will make it look even more expensive.
I think psycological they thing enough people think "a yard is roughly a metre".
Which isn't too bad when talking about linear stuff, but square is where they get people, as 0.9144^2 = 0.83612736m². A pity tricky sellers seldom have any qubic yard stuff to sell as 0.9144^3 = 0.764554857984m³.
