What is the formula to convert linear feet to square feet?

If the width of the material in inches and the linear length in feet are both known, convert the width to a fraction of a foot, then multiply width times length to find square footage. For example, the square footage of a board 6 inches wide and 6 feet long is represented by the formula W (. 5 ft) x L (6 ft) = 3 sq.Click to see full answer. In this way, how many linear feet are in a square foot? Measuring in Square Feet To calculate the area of a room in square feet, you need to make your measurements in feet. For example, the area of a room that measures 12 linear feet by 8 linear feet is 96 square feet.Similarly, how many square feet is 500 linear feet? To find the square footage of a room you multiply the length by the width. So if that room was 500 feet long and zero feet wide then 500 x 0 = 0. but if you have width to the room ,say make it 5 feet wide, then there would be 500 (length) x 5 (width) or 2500 square feet. how do you convert square feet to lineal feet? You determine how many linear feet of flooring you need by multiplying your square footage by 12 and then dividing it by the width of your floor boards. Calculate your square footage by multiplying the length of the space by the width of the space. Measure the width of the flooring boards. How many linear feet are in a 10×10 room?You divide 80 by 8 for the result of 10, which is the measurement of the room’s width in linear feet. To calculate the perimeter, you add two length measurements and two widths. For an 8 by 10 foot room, the perimeter is (8 x 2) + (10 x 2) or 36 linear feet.
