Volume concentration is converted to number concentration by using the volume of a sphere with radius equal to half the median particle size for each bin. The number concentration is then the sphere equivalent number concentration. The absolute magnitute of the PSD will be only approximate if particles are not spherical, but as long as the particles are not expected to significantly change shape with size, the slope of the distribution will be accurate.
