The Genetic Science Learning Center, University of Utah has a nice web gadget that lets you zoom in on various cells to see how large they are compared to each other. Above see a red blood cell, x chromosome, baker’s yeast and (small) e-coli bacterium.

A red blood cell is 8 micron (micro-meter 1/1,000,000 of a meter). E coli is 1.8 microns. Influenza virus is 130 nanometers (1/1,000,000,000 a billionth of a meter). Hemoglobin is 6.5 nanometers. A water molecule is 275 picometers (1 trillionth of a meter).
