Conversion Formula
Å = nm × 10
About Nanometers
A nanometer (nm) is one billionth of a meter (10⁻⁹ m), roughly the width of 3-4 atoms placed side by side. This scale is where nanotechnology operates and is visible light wavelengths are measured. Visible light ranges from about 400 nm (violet) to 700 nm (red). DNA molecules are about 2.5 nm wide, and modern computer processors have transistors as small as 3-5 nm. A human hair is approximately 80,000-100,000 nanometers thick, making one nanometer incredibly tiny by human standards.
About Angstroms
An angstrom (Å) is equal to 0.1 nanometers or 10⁻¹⁰ meters, named after Swedish physicist Anders Jonas Ångström. While not an official SI unit, it remains widely used in chemistry, solid-state physics, and crystallography to express atomic distances and wavelengths. A typical atom has a diameter of 1-3 angstroms, and the spacing between atoms in crystals is commonly measured in angstroms. X-ray crystallographers use angstroms to describe molecular structures with atomic precision.
