How to Convert Square Feet to Feet for Countertops

Write down the total square feet for a single section of countertop. You might have a counter top that is 16 square feet, for example.

Write down all the factors for this number. Factors are number that will divide evenly into the original number. In this example, the factors of 16 are 1, 2, 4, 8 and 16.

Select the numbers that are most likely to be the countertop's dimensions. Use a logical process of elimination to do this. Standard kitchen countertops are approximately 25 inches in depth, which is equal to a little over 2 feet. In this scenario, you can rule out 1 and 16 because a countertop that was 1 foot deep would be quite narrow. Likewise, you would also not likely have a countertop that was 4 feet by 4 feet, unless you were dealing with an island. For a standard countertop, the most likely measurements in feet for this example would be 2 feet deep by 8 feet long.
