Metrics and Sieve Sizes

A #8 stone ranges in size from 2.36 to 9.5 mm (#8 sieve to 3/8 inch). A #16 stone isn't actually a stone but rather fine aggregate larger than a #16 sieve (1/16-inch or 1.18-mm square openings). #467 stone (as defined by ASTM C 33) ranges from 4.75 to 37.5 mm (#4 sieve to 11/2 inches) basically a blend of #4, #6, and #7 stone.

Metrics and Sieve Sizes

Stone size and sieve size are related (the sieve size is basically the minimum size the stone can be), but a stone size is actually an allowable range of sizes. For example, for a #4 stone, will pass through a 50-mm or 2-inch sieve (2x2-inch or 50x50-mm square sieve openings) and at least 95% must be larger than the opening in a #4 sieve.
