Is there a unit of measurement smaller than a nanometer?

Yes Scientists often measure lengths even smaller than a nanometer—the width of an atom, for instance, or the wavelength of a light ray. For this purpose, they use the angstrom (Å or A), equal to 0.1 nanometers. http://www.answers.com/topic/measurement Nov 27 06, 7:39 AM

You mean the smallest distance we can measure? There are measurements smaller than 1 Angstrom - 1 picometer is 100 times smaller, and 1 femtometer (also known as a fermi) is 100,000 times smaller, and is about the size of an atomic nucleus. But there are not any technologies available to practically do anything on that kind of length scale, so the smallest useful scale is about an Angstrom. http://www.newton.dep.anl.gov/newton/askasci/1995/math/MATH098.HTM Nov 27 06, 9:59 AM
