Table 1. Overview of Models to Estimate Particle Volume from Two-Dimensional Metrics, Such As Area or Sizea.
V = volume, A = area retrieved from 2D image analysis, M = major axis of the best-fit ellipse, m = minor axis of the best-fit ellipse, PMP = perimeter of the MP from the 2D image, ki = model calibration parameter. A more detailed explanation of how to use these models is provided as Supporting Information
