About both units

From

Foot

The foot equals 30.48 centimeters exactly and is one of the oldest length units in human history. It is the international aviation standard for altitude — commercial airliners cruise at 35,000 feet. In the US, building dimensions, human height and elevation are all expressed in feet. 1 foot = 12 inches.

Real-world: Airliners cruise at 35,000 ft (10.7 km). Mount Everest is 29,032 ft (8,849 m). A standard US ceiling is 8 ft (2.44 m).

Angstrom

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 foot = 12 inches = 30.48 cm exactly. Knowing feet gives you inches instantly.
For a quick metric estimate, multiply feet by 0.3 — 10 ft ≈ 3 m.
Pilots and air-traffic control use feet globally, even over metric countries.

Avoid these

Writing "6.2 ft" to mean "6 feet 2 inches" — the decimal form is 6.167 ft, not 6.2.
Confusing feet (length) with square feet (area) in US real-estate listings.
Using 0.3 instead of 0.3048 on structural drawings — errors accumulate on multi-storey buildings.
