Estimate the Weight of a Log in Kilograms using Huber's Formula

Spike VM

Calculate the weight of a log using Huber's formula for the cubic metre volume of the log.

The cubic metre volume is calculated from the length of the log and a single diameter measurement on the inside of the bark at mid section.

Enter the the combined oven dry density of wood plus bark for the species and the moisture content you wish to calculate for.

List below contains the value's for average dry densities of wood plus bark and the average green moisture content for some of North America's Tree Species.
