About Angstrom
The angstrom (Å) equals 10⁻¹⁰ metres, or 0.1 nanometres — roughly the diameter of a hydrogen atom, which is why it survives in crystallography and spectroscopy.
Common uses: crystallography, atomic physics, semiconductors.
About Inch
The inch is an imperial unit equal to 1/12 of a foot or 2.54 centimeters. It is widely used in the US and UK for small measurements.
Fun Fact: The inch was historically defined as the width of a man's thumb.
Common uses: screen sizes, construction, clothing.
