You cannot.
A linear foot is a measure of length or distance in 1-dimensional space while a square foot is a measure of area in 2-dimensional space. The two measure different things so the above measures, which are derived from them also measure different things. According to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
You can't convert that.
A linear foot is a unit of distance. A square foot is a unit of area. The two units are therefore incompatible.
You can't. A square foot is a measure of area. a regular, linear foot is a measure of length. The two units are completely incompatible.
Multiply by 144, since there are 144 square inches in a square foot (12x12).
You can't convert that. You can convert linear units to linear units, square units to square units, or cubic units to cubic units.
Pounds per square foot x 0.006944 equals psi

You can't, they are incompatible units. 16 foot x 16 foot = 256 square foot
Miles per hour (mph) is a unit of speed, while pounds per square foot (psf) is a unit of pressure. The two units measure different physical quantities and cannot be directly converted from one to the other.

The foot is a linear measurement. You cannot convert a linear measurement to an area measurement.
A square foot is a unit of area. A linear foot is a unit of length. The two units are therefore incompatible.
A linear foot is a unit of length. A square metre is a unit of area. The two units are therefore incompatible.
