Enter the gravel area (ft^2) and the gravel depth (in) into the Gravel Weight Calculator. The calculator will evaluate the Gravel Weight. 

Gravel Weight Formula

The following two example problems outline the steps and information needed to calculate the Gravel Weight.

GW = GA * GD/12 * 106.1275


  • GW is the Gravel Weight (pounds)
  • GA is the gravel area (ft^2) 
  • GD is the gravel depth (in) 

How to Calculate Gravel Weight?

The following steps outline how to calculate the Gravel Weight.

  1. First, determine the gravel area (ft^2). 
  2. Next, determine the gravel depth (in). 
  3. Next, gather the formula from above = GW = GA * GD/12 * 106.1275.
  4. Finally, calculate the Gravel Weight.
  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.

gravel area (ft^2) = 500

gravel depth (in) = 3

GW = GA * GD/12 * 106.1275 = ?
