The Weight Per Square Foot Calculator is a practical tool used to determine the weight distribution over a given area. This calculation is commonly applied in construction, material science, and engineering to analyze loads, material weights, and floor strength.

It is especially helpful for assessing weights of materials like steel, concrete, aluminum, or granite over specific surface areas.

Formula:

$WSF = W / A$

Variable	Description	Unit
$WSF$	Weight per square foot	lbs/sq ft or kg/m²
$W$	Total weight	lbs or kg
$A$	Total area	sq ft or m²

Solved Calculations:

Example 1: Calculate Weight Per Square Foot for a 100 lbs Object Over 20 sq ft

Step	Value	Explanation
Total Weight ($W$)	$100 \, \text{lbs}$	Given
Total Area ($A$)	$20 \, \text{sq ft}$	Given
Calculation	$WSF = 100 / 20$	Divide weight by area
Result	$WSF = 5 \, \text{lbs/sq ft}$	Weight per square foot

 

Example 2: Calculate Weight Per Square Meter for 50 kg Over 4 m²

Step	Value	Explanation
Total Weight ($W$)	$50 \, \text{kg}$	Given
Total Area ($A$)	$4 \, \text{m²}$	Given
Calculation	$WSF = 50 / 4$	Divide weight by area
Result	$WSF = 12.5 \, \text{kg/m²}$	Weight per square meter
