Angstrom Unit

An Angstrom (Å) is a unit of length used primarily to measure extremely small distances, such as atoms and molecules. One Angstrom equals 10^-10 meters, which is one ten-billionth of a meter. To put it in perspective, atoms are roughly a few Angstroms in size. The unit helps scientists describe the sizes of tiny structures in physics, chemistry, and biology with great precision, making it easier to understand and communicate about the microscopic world.
