1 micrometre

To help compare different orders of magnitude this page lists some items with lengths between 10-6 and 10-5 m (between 1 and 10 micrometres, or µm).

Distances shorter than 1 µm Distances longer than 10 µm
 * 1 µm &mdash; the side of square of area 10-12 m²
 * 1 µm &mdash; edge of cube of volume 1 fL
 * 1 µm &mdash; the limit of resolution for conventional Photolithography techniques
 * 1-10 µm &mdash; diameter of typical bacterium
 * 1.55 µm &mdash; wavelength of light used in optical fibre
 * 3-4 µm &mdash; size of a typical yeast cell
 * 6 µm &mdash; anthrax spore
 * 6-8 µm &mdash; diameter of a human red blood cell
 * 7 µm &mdash; diameter of the nucleus of typical eukaryotic cell
 * 7 µm &mdash; width of strand of spider web
 * 8 µm &mdash; width of a chloroplast
 * about 10 µm &mdash; size of a fog, mist or cloud water droplet
