Enter the density of the material and its thickness into the calculator to determine the weight per square meter. This calculator helps in determining the weight of a material per area which is useful in various engineering and construction applications.

Weight Per Square Meter Formula

The following formula is used to calculate the weight per square meter.

W = ρ * t

Variables:

  • W is the weight per square meter (kg/m²)
  • ρ (rho) is the density of the material (kg/m³)
  • t is the thickness of the material (meters)

To calculate the weight per square meter, multiply the density of the material by its thickness.

What is Weight Per Square Meter?

Weight per square meter is a measure of the weight of a material spread over a unit area. It is commonly used in the fields of materials science, engineering, and construction to specify the weight of materials for various applications. Knowing the weight per square meter is essential for calculating load-bearing capacities, material requirements, and transportation costs.

How to Calculate Weight Per Square Meter?

The following steps outline how to calculate the Weight Per Square Meter.


  1. First, determine the density of the material (ρ) in kilograms per cubic meter.
  2. Next, determine the thickness of the material (t) in meters.
  3. Next, gather the formula from above = W = ρ * t.
  4. Finally, calculate the Weight Per Square Meter (W) in kilograms per square meter.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.
