    The exact definition of sand varies. The scientific Unified Soil Classification System used in engineering and geology corresponds to US Standard Sieves, and defines sand as particles with a diameter of between 0.074 and 4.75 millimeters. By another definition, in terms of particle size as used by geologists, sand particles range in diameter from 0.0625 mm (or ​ ⁄16 mm) to 2 mm. An individual particle in this range size is termed a sand grain. Sand grains are between gravel(with particles ranging from 2 mm up to 64
