100 microns equals to 0.004 inches
100 microns equates to 100ppm
The smallest wire on a chip is measured in microns. Current chips have wires that are less than one micron wide, while a human hair is about 100 microns thick.
There is no direct conversion from microns to grains of weight. A micron is a measure of distance equal to one millionth of a meter. In air filtering this is the dimension of the diameter of the particle. Grains are measures of weight. You can't determine the weight of say a 5 micron particle unless you know what the particle is made of. It is even difficult to express any average since the material captured in an air filter in Arizona will be much different than in Los Angeles. The volume of a spherical particle is So the volume of a particle with diameter 5 microns = 6.54 cu-microns or 6.54 x 10-17 cubic-meters If the material was silica sand with a density of 2.17 Mg/cu-m you would have 1.42 x 10-10 grams. 1.0 gram = 15.43235 grains So a 5 micron particle of filered sand = 2.19 x 10-9 approx 2.2 billionths of a grain
vacuum is measured in pressure. To get a vacuum you need a negative pressure. that would be inches of mercury hg
1 millivolt
There are 60 seconds in one minute. Therefore, 1200 seconds is equal to 1200/60 = 20 minutes.
1 mm = 1000 000 microns 0.1 mm = 100 000 microns
100 micrometers (microns) equals 0.01cm
3.937 thousandths of an inch
100 microns is 20 times thicker than 5 microns
millionths of what, if inch then 2.54 microns if metre then 100 microns
100 microns = 3.93700787 mils
149 microns is 100 mesh
80 microns
100 microns is 3937 millionths of an inch
10 microns = 0.01 millimeters
3 microns is about 0.00011811 inches.
200 microns is about 0.007874016 inches.
