Powder Mesh Sizes
Table to convert US and European units of powder particle size (granulometry) – Mesh / Sieve / Microns / mm / inches.
Most of our food ingredients are in the range 20-200 Mesh

Larger sieve openings (1 in. to 1/4 in.) have been designated by a sieve “mesh” size that corresponds to the size of the opening in inches. Smaller sieve “mesh” sizes of 3 1/2 to 400 are designated by the number of openings per linear inch in the sieve. The following convention is used to characterize particle size by mesh designation: a “+” before the sieve mesh indicates the particles are retained by the sieve; a “-” before the sieve mesh indicates the particles pass through the sieve; typically 90% or more of the particles will lie within the indicated range.
For example, if the particle size of a material is described as -4 +40 mesh, then 90% or more of the material will pass through a 4-mesh sieve (particles smaller than 4.76 mm) and be retained by a 40-mesh sieve (particles larger than 0.420 mm).
If a material is described as -40 mesh, then 90% or more of the material will pass through a 40-mesh sieve (particles smaller than 0.420 mm).
