To help compare different orders of magnitude this page lists lengths between 10⁻⁷ and 10⁻⁶ m (100 nm and 1 µm).

100 nm — 90% of particles in wood smoke are smaller than this.
120 nm — greatest particle size that can fit through a ULPA filter
120 nm — diameter of a human immunodeficiency virus (HIV) ^[3]
125 nm — standard depth of pits on compact discs (width: 500 nm, length: 850 nm to 3.5 µm)
180 nm — typical length of the rabies virus
200 nm — typical size of a Mycoplasma bacterium, among the smallest bacteria
280 nm — near ultraviolet wavelength
300 nm — greatest particle size that can fit through a HEPA (High Efficiency Particulate Air) filter (N100 removes up to 99.97% at 0.3 micrometres, N95 removes up to 95% at 0.3 micrometres)
380–420 nm — wavelength of violet light (see color and optical spectrum)
420–440 nm — wavelength of indigo light
440–500 nm — wavelength of blue light
500–520 nm — wavelength of cyan light
520–565 nm — wavelength of green light
565–590 nm — wavelength of yellow light
590–625 nm — wavelength of orange light
625–740 nm — wavelength of red light
700–1400 nm — Wavelength of near-infrared radiation
