Linear foot to square foot

Hello guys.

Two square feet equals how many linear feet ???.


Most roofers only deal in square feet. Atleast all the ones i know of. Atleast when measuring a roof. Linear is used when replacing wood normally 1x materials.

A little more than a pound of feathers. :?

It does not work like that. Square feet defines area and lineal feet defines distance. Afterall, two square feet of sewing thread could equal hundreds of lineal feet when laid out. Now, if you are talking about wood, you need to specify lineal feet of 2x6, 2x8, etc., or just use board feet.

ex. Two board foot of 1x12 pine = 2 lineal ft. of 1x12 pine

That would be correct if it is true 1 x 12; however, if it is milled down that equation changes.

That is true since a 1 by is not a true a 1 by.

arrrrgghhh, I knew some smart azz would say that! :smiley:

FYI, I always round UP.
