About both units

From

Inch

in

The inch equals 2.54 centimeters exactly since 1959. It is the global standard for screen diagonal sizes — a "55-inch TV" has a 139.7 cm diagonal. Pipe diameters, US and UK shoe sizes, and hard-drive form factors are all specified in inches. 1 inch = 1/12 foot = 1/36 yard.

Real-world: A 65-inch TV has a 165 cm diagonal. A smartphone screen is typically 6–7 inches. Standard copper plumbing in the UK is ½ inch or ¾ inch.

Angstrom

Å

The angstrom equals 10⁻¹⁰ meters or 0.1 nanometers. It is used in chemistry and crystallography for atomic and molecular dimensions. The Bohr radius — the characteristic size of a hydrogen atom — is 0.529 Å. Covalent bond lengths are typically 1–2 Å.

Real-world: A water molecule is about 1 Å across. The covalent bond in H₂ is 0.74 Å. X-ray wavelengths are 0.1–100 Å.

Tips & common mistakes

Quick tips

  • 1 inch = 2.54 cm exactly by international agreement — no rounding.
  • Screen sizes are always diagonal, never width. A 27-inch monitor is about 60 cm wide.
  • To convert cm to inches mentally, divide by 2.5 and subtract 1.6%.

Avoid these

  • Reading a screen size as width. A 65-inch TV is about 143 cm wide — the 165 cm figure is diagonal.
  • Using 2.5 instead of 2.54 on precision drawings — the 1.6% error matters in manufacturing.
  • Confusing inches of length with inches of mercury (inHg) — a pressure unit, not length.

Frequently asked questions
