What is a femtometer used to measure?

A femtometer measures extremely small lengths typical in nuclear and particle physics, such as sizes of atomic nuclei and nuclear interactions.

What does an angstrom measure?

An angstrom is used to express atomic and molecular scale distances, like atomic radii, bond lengths, and lattice spacings.

Why do femtometer to angstrom conversions yield very small numbers?

Because a femtometer is much smaller than an angstrom, conversion results in very small decimal values reflecting scale differences.
