Are there charts that go past 22" DBH? How do others calculate the approximate volume in larger trees, if at all. Id think log trees would have to be. Firewood, trees...most probably don't care Lets say I had a 27" DBH tree. If i take the circumference 27 x 3.14 = 84.78, and divide it by the circumference of the 22" tree 22 x 3.14 = 69.08, 84.78/69.08 i get 1.23 So 1 cord x 1.23 = 1.23 cords in the 27" tree.
