How thick is 100 microns approximately?

The correct answer highlights that 100 microns is approximately equal to 0.1 millimeters, which is essential for understanding measurements in practical applications and scientific contexts.

To clarify, one micron (or micrometer) is one-thousandth of a millimeter, so 100 microns translates directly to 0.1 millimeters (as there are 1,000 microns in a millimeter). This small measurement is often used in various fields, including materials science and engineering, where precision is crucial.

In practical terms, a business card usually has a thickness of about 200-300 microns, which makes it significantly thicker than 100 microns. A sheet of computer paper typically has a thickness of around 90-120 microns, making option B a more accurate comparison. The thickness of 2 inches is dramatically greater than 100 microns, as there are 25,400 microns in an inch. Understanding these comparisons helps in visualizing the size of various materials and components.
