Typical size of contaminants and particles are indicated below. Note that the values varies widely depending on how the products are processed. By example milling corn starch in 30 minutes can reduce the average diameter of starch particles from 10 to 0.3 microns (μm, 10 -6 m). Further milling may produce particles even smaller than 0.1 microns.

A cobble is a clast of rock with a particle size of ~2.5 to 10 inches or 6-25 cm, based on the Krumbein phi scale of sedimentology. Cobbles are generally considered to be larger than pebbles (4 to 64 millimetres diameter) and smaller than boulders (greater than 256 millimetres diameter, or generally, 30 cm/1 foot [1 meter is 3 feet]).
