This last weekend we brought home a nice piece of oak and we're trying to estimate the weight of the wood. The piece is roughly 32" in diameter and 22" thick. Does anyone have a formula for calculating this? Thanks Dave

the volume of a cylinder is pi * r * r * h, where r is the radius and h the length of the cylinder. Plugging in 16 and 22, I get 17,693 cubic inches, or 10.24 cubic feet. To find weight, multiply one of these figures by the density of oak (in the correct units, pounds per cubic inch, etc). I'll look it up tonight if no one else chimes in today. Mike | |||||

From ASTM D143 at 12% moisture content, Northern Red oak is 44 lbs/ft�
White Oak is 48 lbs/ft�.

Thanks for the figures. We estimated it at around 300lbs, but looks like we missed it a bit. We hauled the oak about 30 miles in the back of our '71 VW Squareback - it certainly did load the back down. Dave | |||||

Once you've got the volume in cu. ft. you can start getting an estimate
of the weight if you know that 1 cu. ft. of water weighs 62.5 lbs. All
you then have to judge is what proportion of the timber is above the
water when it floats. If you'd said 75% I don't think you would have
been too far out.
