1 micrometre

From Wikipedia, the free encyclopedia

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

• 1 µm — the side of square of area 10⁻¹² m²
• 1 µm — edge of cube of volume 1 fL
• 1 µm — the limit of resolution for conventional Photolithography techniques^{[citation needed]}
• 1-10 µm — diameter of typical bacterium
• 1.55 µm — wavelength of light used in optical fibre
• 3-4 µm — size of a typical yeast cell
• 3–5 µm — size of a human spermatozoon's head (radius by length)^{[citation needed]}
• 6 µm — anthrax spore
• 6-8 µm — diameter of a human red blood cell
• 7 µm — diameter of the nucleus of typical eukaryotic cell
• 3-8 µm — width of strand of Spider web silk^[1]
• 8 µm — width of a chloroplast
• about 10 µm — size of a fog, mist or cloud water droplet

Distances longer than 10 µm
