In order to use an online calculator to convert square feet to linear feet, two basic measurements must be known. The first is the width in inches of the material being measured. The second is the square footage.
Type the width measurement into the appropriate box on the online calculation. Do the same with the square feet. Click the calculate or total button, and the linear feet will appear. For instance, if one is calculating the amount of flooring needed for several rooms in a house, some online calculators have multiple lines so that the entire amount of linear feet can be calculated all at once.
