A centimeter (cm) is 10,000 nanometers. Therefore, a nanometer is 10,000 times smaller than a centimeter. ... One millimeter (mm) is one million nanometers.

What is smaller than a nanometer?

Atoms are smaller than a nanometer. One atom measures ~0.1-0.3 nm, depending on the element.

Which is smaller millimeter or nanometer?

Notice that the nanometer is three orders of magnitude smaller than the micrometer, which is three orders of magnitude smaller than the millimeter, which is three orders of magnitude smaller than the meter. Therefore, one nanometer is 1/1,000,000,000 of a meter. Identify and label the nm.
