Millimeter, micron, inch, mesh count comparison table

Micron um is a commonly used unit of length and is used in many important occasions. It is a very short length, so especially in some places where the requirements are very accurate, micron is an extremely important length. Let’s learn about the conversion and related knowledge of microns and common units!

Introduction to Micron:

Micron is a unit of length, the symbol: μm, and μ is pronounced as muu. 1 micron is equivalent to one thousandth of 1 mm.

Micro: One millionth of the main unit:_{Rice |}An | ~ Farah.

Microns and commonly used units conversion:

1m = 10³mm

1m = 100cm

1cm = 10mm

1mm = 10³um

1um = 10³nm

1nm =10³pm

Example:

Matter Diameter Length

Platelets 1.5 micrometers

Red blood cells 4.5 microns

Leukocytes 8 micrometers

Lymphocytes 14 micrometers

Sand 300 micrometers

Chloroplast 100 micrometers

Misty droplets 400 micrometers

Hair 80 micrometers

Correlationship between the number of powder mesh and microns:

1 micron--------12500 mesh

1.3 microns right----------8000 mesh

2 microns------------6250 mesh

2.6 microns----------5000 mesh

5 microns-----------2500 mesh

6.5 microns----------2000 mesh

10 microns---------1250 mesh

15 microns-------------800 mesh

20 microns-------------------------------------------------------------------------------------------------------------------------

33 microns----------425 mesh

37 microns-----------400 mesh

74 microns-------------------------------------------------------------------------------------------------------------------------

149 microns----------100 mesh

350 microns------------45 mesh

Inches and millimeters correspondence

1 inch equals 25.4 mm.

Inches are units of measurement for the length of the imperial system. Centimeters and millimeters are international units of measurement of length.

Because 1 inch = 2.54 cm, and 1 cm = 10 mm,

So 1 inch = 2.54 cm = 2.54x10 mm = 25.4 mm.

That is, 1 inch equals 25.4 mm.

Number of mesh:

The object refers to the number of holes per inch of the screen. 50 mesh means that there are 50 holes per inch and 50 holes per square inch.50=2500; 500 mesh means that there are 500 holes per inch and 500 holes per square inch.500=250,000. The higher the number of mesh, the more holes. In addition to representing the holes of the screen, it is also used to represent the particle size of particles that can pass through the screen. The higher the mesh, the smaller the particle size. Our country uses American standards.
