How do i convert square foot to linear foot?

Answer 1

You cannot. A linear foot is a measure of length in 1-dimensional space while a square foot is a measure of areain 2-dimensional space. The two measure different characteristics and, according to the most basic principles of dimensional analysis, any attempt at comparisons or conversions between the two are fundamentally flawed.

Answer 2

They are two different types of units. You cannot convert between area and length.
