William Klemme

Spike VM

Klemme calculates the volume of a log in cubic meters and is used to scale logs for export to the People's Republic of China.

Average diameters have to be calculated from both ends of the log.
Diameters measured to the nearest mm need to be rounded to the nearest whole centimetre.

Spike VM
for the large end 29.7 + 31.3 = 61 / 2 = 31.5 cm enter as 32 for large end diameter
for the small end 26.9 + 29.3 = 56.2 /2 = 28.1 cm enter as 28 for the small end diameter

Diameter Measured Inside Bark = DIB
Length of Log in Metres M
DIB Measured Small End cm
DIB Measured Large End cm
