About These Units

Angstrom (Å)

Named after Anders Jonas Ångström, the angstrom is equal to 10⁻¹⁰ meters. It's commonly used in atomic physics, chemistry, and crystallography.

Nanometer (nm)

Equal to 10⁻⁹ meters, the nanometer is an SI unit widely used in nanotechnology, biology, and materials science.

Conversion Formulas

Å to nm: divide by 10

nm = Å ÷ 10

nm to Å: multiply by 10

Å = nm × 10

Understanding Angstroms and Nanometers

What are Angstroms?

The angstrom (Å) is a unit of length equal to 10⁻¹⁰ meters. It was named after the Swedish physicist Anders Jonas Ångström and is commonly used to measure atomic radii, wavelengths of electromagnetic radiation, and distances between atoms in crystals.

Why Use Angstroms?

  • Perfect scale for atomic measurements
  • Traditional in spectroscopy
  • Close to Bohr radius scale
  • Convenient for crystal lattice parameters

Nanometers vs Angstroms

While both units measure very small lengths, nanometers are part of the International System of Units (SI), making them more standardized. However, angstroms remain popular in specific scientific fields due to their convenient scale for atomic phenomena.

Scale Comparison

  • 1 meter = 10¹⁰ angstroms
  • 1 meter = 10⁹ nanometers
  • 1 nanometer = 10 angstroms
  • 1 angstrom = 0.1 nanometers

Historical Note: The angstrom was originally defined based on the wavelength of the red line of cadmium, but is now defined in terms of the meter.
