Square Feet to Tons Calculator

The Square Feet to Tons Calculator allows you to calculate the number of tons needed based on area, thickness, and material density. This is particularly useful for construction, landscaping, and material ordering.

Square Feet to Tons Formula

To convert square feet into tons, use the formula:

\[ T = A \times \frac{Th}{12} \times D \]

Where:

• \( T \) is the total weight in tons
• \( A \) is the area in square feet
• \( Th \) is the thickness in inches
• \( D \) is the density of the material in tons/ft³

Example Calculations

1. Gravel:
   If you are covering 100 square feet with a 4-inch thickness of gravel (density = 0.05244 tons/ft³):

   \[ T = 100 \times \frac{4}{12} \times 0.05244 = 1.748 tons \]

2. Mulch:
   For 200 square feet at 3-inch thickness using mulch (density = 0.022 tons/ft³):

   \[ T = 200 \times \frac{3}{12} \times 0.022 = 0.11 tons \]

Material Densities

• Gravel = 0.05244 tons/ft³
• Mulch = 0.022 tons/ft³
