Standard in manufacturing and consumer specs in the US, including displays and lumber. Defined metrically for exact conversions.

  • Symbol: in
  • System: Imperial/US customary
  • Exact relations: 1 in = 25.4 mm = 2.54 cm = 0.0254 m (exact)
  • Other relations: 12 in = 1 ft, 36 in = 1 yd
  • Typical examples: screen sizes, pipe/nominal lumber sizes, drill bits
To unit

Picometer (pm) — SI unit equal to one trillionth of a meter

Used to express atomic and subatomic dimensions such as bond lengths and ionic/atomic radii in chemistry and materials science

  • Symbol: pm
  • System: SI derived unit
  • Exact relations: 1 pm = 10⁻¹² m = 0.001 nm = 10⁻⁶ µm = 0.01 Å = 1,000 fm
  • Imperial/US equivalents: 1 pm ≈ 0.00000000003937007874 in
  • Typical examples: covalent bond lengths ~100–200 pm; Bohr radius of hydrogen ~53 pm; atomic radii tens to a few hundred pm
