Enter the granite length (ft), the granite width (ft), and the granite thickness (in) into the Granite Weight Calculator. The calculator will evaluate the Granite Weight. 

Granite Weight Formula

The following formula is used to calculate the Granite Weight. 

GRN = GL * GW * GT/12 * 175


  • GRN is the Granite Weight (lb)
  • GL is the granite length (ft) 
  • GW is the granite width (ft) 
  • GT is the granite thickness (in) 

How to Calculate Granite Weight?

The following steps outline how to calculate the Granite Weight.

  1. First, determine the granite length (ft).
  2. Next, determine the granite width (ft). 
  3. Next, determine the granite thickness (in). 
  4. Next, gather the formula from above = GRN = GL * GW * GT/12 * 175.
  5. Finally, calculate the Granite Weight.
  6. 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.

granite length (ft) = 10

granite width (ft) = 10

granite thickness (in) = 3

GRN = GL * GW * GT/12 * 175 =  ?
