Calculate weight per square foot, total weight, or total area using an explicit solve mode and two inputs, with support for pounds, kilograms, tons, sq ft, sq m, and sq yd.

Average mass per area. This does not check floor or structural capacity. Tons mean US short tons (2,000 lb).

Weight per Square Foot Formula

The following two example problems outline the steps and information needed to calculate the Weight per Square Foot.

WSF = W / A

Variables:

  • WSF is the Weight per Square Foot (lbs/ft^2)
  • W is the total weight (lbs) 
  • A is the total area (ft^2) 

To calculate weight per square foot, divide total weight by total area in compatible units. This tool reports average mass per area, not a structural capacity check. Tons mean US short tons of 2,000 lb.

How to Calculate Weight per Square Foot?

The following steps outline how to calculate the Weight per Square Foot.

Example Problem #1:

  1. First, determine the total weight (lbs).
    • The total weight (lbs) is given as 300.
  2. Next, determine the total area (ft^2).
    • The total area (ft^2) is provided as 10.
  3. Finally, calculate the Weight per Square Foot using the equation above: 

WSF = W / A

The values provided above are inserted into the equation below and computed.

WSF = 300 / 10 = 30.00 (lbs/ft^2)

Example Problem #2: 

For this problem, the variables required are provided below:

total weight (lbs) = 200

total area (ft^2) = 20

Test your knowledge and check your answer with the calculator.

WSF = W / A = ?
