The estimate of cell biovolume, based on measurements of linear dimensions of shapes adapted to standard geometric models, is important for the study of phytoplankton ecology. However, time-consuming calculations are required for the estimation of biovolume from linear measurements. In this paper, a simple, user-friendly multiplatform software tool is presented to aid in the calculation of the biovolume of phytoplankton samples, using geometric models and conventional microscopic observations. The software implements the most recent formulae available in the literature for calculating cell biovolume on the basis of a set of 31 geometric shapes.
