From unit

Nanometer (nm) — SI unit equal to one billionth of a meter

Used for wavelengths of light, molecular structures, and semiconductor features where dimensions are far below the micrometer scale

  • Symbol: nm
  • System: SI derived unit
  • Exact relations: 1 nm = 10⁻⁹ m = 0.001 µm = 10 Å
  • Imperial/US equivalents: 1 nm ≈ 0.0000000393700787 in
  • Typical examples: visible light ~400–700 nm; DNA double helix diameter ~2 nm; advanced transistor features on the order of single-digit nanometers
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
