Burt's Quarter Girth Method

Spike VM

A version based on the Hoppus method known as the Burt's Quarter Girth Method formula for calculating the true volume of a log.

Burt's Quarter Girth Formula

Formula used:
V = G² ÷ 4 * L ÷ 113
V = volume
G = girth measured mid length of the log
L = length of log in feet

Length of Log in Feet ft
Girth in Inches in

Results:

Cubic Feet ft³

Calculation

  1. the length of the log in feet
  2. the circumference of the log taken mid-length measured in inches

Result

  1. volume of log

Burt's Average Diameter

Formula used:
V =  ((Dt + Db)  ÷ 2 )² * L ÷ 183
V = volume of log
Dt = diameter top end log
Db = diameter large end of log
L = length of log

Length of Log in Feet ft
Diameter of Log Large End in
Diameter of Log Top End in

Results:

Log Volume in Cubic Feet ft³

Calculation

  1. the length of the log in feet
  2. diameter large end of log
  3. diameter top end of log

Result

  1. volume of the log
