How to work out m3 of a round log.

[openspaceman]

Is there such a calculation for hoppus cubic meter

 

I don't understand the question but 1m3 of solid wood is 27.736 Hft IIRC.

I have always rounded to; 30 hoppus feet is 1.0 cubic meter. Which in beech terms is one ton. I worried when a beech butt measured over ninety cube as I knew we'd have trouble moving it because it weighed in at over three tons.

Am I right in thinking that if you can multiply the m3 of a round log by 0.7852 and that will give you the hoppus m3

 

But you don't need to do that. You can just work out the hoppus metre straight off without having to do one calc just to convert it to another value.

 

Hoppus metre calculation:

 

(3m x 1m diameter log)

 

3.14 (girth) divided by 4 - 0.785

0.785 x 0.785 (quarter girth, squared) - 0.616

0.616 x 3 (length) - 1.848 hoppus metres in the log

A couple of pics to show scale. I hired in some help for the bigger pieces I knew I'd have trouble with! One section of the beech, laying on the road, was 30 cube. The other pic shows 90 cube standing. We used gravity and rolled it, in similar sections, down to the road where the big machine then carted it up to the loading bay.
