how do you figure out volume

I just heard this week that the fluff factor of chipping logs is 2.8. Not sure how accurate it is but when I tested it using a green wood weight chart against what I figure chips weigh I thought it was close!

Only the volume of the stump could be learned from the dbh. Some days I amaze myself.

could you explain a bit more....are you saying a solid cubic foot off wood when chipped is 2.8 cubic feet of chip because it is fluffy
or
if you have a foot of wood and get fluffed you now have 14.8 inches

Ha ha I heard the first. If you chip a square foot of wood you get 2.8 square feet of chips. Not sure how accurate but is a nice starting point!

Assuming constant taper, you could use the volume of a cone for a conifer trunk.

Woodweb has log volume, weight, and lumber board footage tables. Extremely handy to have, for estimating log weights when craning, and board footage when prepping logs for mill sale.

Clearly, the OP meant that chipped logs consume 2.8 times more volume than whole. Sounds about right, as the average weight of a yard of chips is 550 lb, but a yard of doug fir would weigh about 1300 lb......
Conversely, of course, chipped crown material will consume far less space than loose. Certainly a reduction of 3-6x depending on how densely it was piled prior to chipping....
