Size of Particle - an overview ScienceDirect Topics

Particle sizes are measured in microns (μ). A micron is 1/1000 mm. or 1/25,400 in. A millimicron (mμ) is 1/1000 of a micron, or 1/1,000,000 mm. Usually particle size is designated as the average diameter in microns, although some literature reports particle radius. Particle concentration is often expressed as grains per cubic feet of gas volume.
