How big are oxygen particles
WebThe D50 number mean that 50% of the particles that were measures are larger than this number, and 50% were smaller. So, if a particle when measured you may have a D50 of, say, 4 microns. (Usually written as D50= 4 microns.) This means half the particles were over 4 and half were under. WebThere are 25,400 microns in one inch. This dot (.) is approximately 1/64 of an inch wide and equals 615 microns.
