How many microns is a virus?

Answer 1

Viruses typically range from about 20 to 300 nanometers (nm) in size, which is equivalent to 0.02 to 0.3 microns (µm). Some larger viruses, like the giant mimivirus, can be up to 800 nm (0.8 µm). However, most viruses fall within the smaller range, making them significantly smaller than most bacteria.
