Calculating tonnage is a two-step process using Topolyst and Reckon. First, the density information must be formatted and entered correctly into the “Volume” file in Topolyst/LP360. This file can be named anything but for our instructions it is the Volume file you see in the figures below.
Secondly, Reckon will calculate the tonnage from the volume and density when uploading the volume file to Reckon. Once posted to Reckon, the density weights are displayed in Reckon and can then be downloaded to a .csv file or PDF report.
