T. Heikkilä. (1927). Über die Ermittelung der Querfläche eines Stammes. Acta Forestalia Fennica vol. 32 no. 3 article id 7208. https://doi.org/10.14214/aff.7208
English title: On examining the cross-sectional area of a stem.
Original keywords: Querfläche; Formel; Stamm
English keywords: cross-sectional area; formula; stem

Because the cross-sectional area of a tree stem is ellipsis, it cannot be determined exactly with only the diameter measurement.  The article presents a formula and the calculation of the exact cross-sectional area. If the cross-sectional area is calculated as arithmetic mean of two diameter measurement, varies the error between two limit values. The error becomes smallest by calculating the area based on the biggest and the smallest diameter measurements.
