Enter the log radius (ft) and the log length (ft) into the Green Log Weight Calculator. The calculator will evaluate the Green Log Weight. 

Green Log Weight Formula

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

GLW = pi*r^2*L*85


  • GLW is the Green Log Weight (lb)
  • r is the log radius (ft) 
  • L is the log length (ft) 

How to Calculate Green Log Weight?

The following steps outline how to calculate the Green Log Weight.

  1. First, determine the log radius (ft). 
  2. Next, determine the log length (ft). 
  3. Next, gather the formula from above = GLW = pi*r^2*L*85.
  4. Finally, calculate the Green Log 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.

log radius (ft) = 3

log length (ft) = 10

GLW = pi*r^2*L*85 = ?
