Particle size definition

Particle size means the diameter (in millimeters) of a soil or sand particle, usually measured by sedimentation or sieving methods.
Particle size means the polystyrene latex (PSL) light-scattering equivalent size of particulate matter as expressed as a diameter in micrometers (μm).
Particle size means the size of a particle as determined by its smallest projected dimension, usually expressed in micrometers (microns).
