The link below will give the density of wood. You can find an estimation of the stick volume in cubic foot by:

(Pi * R^2) * H = Volume

Pi of course is 3.14159

R is half the diameter of the stick

H is the length of the stick

This volume would be an estimate because of the taper and the bead of the stick. As you notice on the web site below, the density of wood has a range as Grunters dad said, it is not an exact number.

Volume * density will give you the weight of the stick.

But this estimate is good enough for you to compare the weights of one stick to another. The web site has the density of wood in both kilograms/ meter^3 and in pounds/ foot^3.
