What is an Angstrom?
One angstrom unit (A.O. or )= 0.1 nanometers, or one ten-thousandth of a micron (10-4 microns), or one hundred-millionth of a centimeter (1 x 10-8 cm.) One angstrom is the diameter of a hydrogen atom — the smallest element known.

If you thought the nanometer was small, you haven’t met the angstrom, but that’s probably because it preceded the nanometer. Named after Swedish spectroscopist and physicist Anders Angstrom (1814-1874), the angstrom is a legacy unit of measurement that equals one ten-billionth of a meter, or 1/10,000,000,000 of 3.28 feet. Put another way, it would take 245-million angstroms to equal one inch, 10-million angstroms to equal one millimeter, or 10,000 angstroms to equal one micron. And by now you’ve guessed that with a nanometer being one-billionth of a meter, it takes 10 angstroms to equal one nanometer. In 1868 Anders Angstrom was studying solar radiation and compiled a chart of electromagnetic energy that measured light waves in increments of one ten-millionth of a millimeter. It was this unit of measurement that became known as the angstrom. Though the angstrom has been replaced by the nanometer as the unit of choice, it was traditionally used to measure very small objects such as atom
