A less dramatic but still significant depletion of. ozone levels was recorded around the globe. With less. ozone in the atmosphere, more ultraviolet (UV) radia-. tion strikes Earth, causing more skin cancer, eye dam-. age, and possible harm to crops.
There are 1.0E-6 meter in a micrometer. 1 Micrometer is equal to 1.0E-6 Meter. 1 um = 1.0E-6 m. A micrometer, or micron, is a unit of length sometimes used in SI as a 1Ã10â6 of a meter. This is a quite specific measurement unit used in science (i.e. for measuring various types of wavelength, etc.) or in industrial technology.
Micron. A unit of measure for the smallest of the small, One Micron is 0.001 mm or 0.00004 inch. A micron is really, really small. The width of a human hair is about 70 microns. Our eyes can see no smaller than 40 microns, and youâll need a decent microscope to see a particle 20 microns wide. Allergens like dust, smoke and bacteria are particulates that are often .3 microns or less. At that size, they can get deep into your lungs, because they arenât filtered well by your nose and throat.
