Smoot - humorous nonstandard length unit

Smoot is a nonstandard, humorous unit of length equal to 5 ft 7 in, the height of Oliver R. Smoot (MIT ’62). Used to measure the Harvard Bridge in 1958 as “364.4 smoots ± 1 ear” and referenced in engineering culture and local markings

  • Symbol: none standardized (sometimes sm or smt)
  • System: Informal/non-SI
  • Exact relations: 1 smoot = 5 ft 7 in = 67 in (exact)
  • Metric equivalents: 1 smoot = 67 × 0.0254 m = 1.7018 m (exact)
  • Typical examples: Harvard Bridge markings at 10-smoot intervals; humorous unit conversions in campus lore

Micrometer (µm) — SI unit equal to one millionth of a meter

Used in precision engineering, microscopy, and semiconductor manufacturing for dimensions far below a millimeter

  • Symbol: µm (also called micron)
  • System: SI derived unit
  • Exact relations: 1 µm = 10⁻⁶ m = 0.001 mm = 10⁻⁴ cm
  • Imperial/US equivalents: 1 µm ≈ 0.0000393700787 in
  • Typical examples: human hair ~70 µm; bacteria ~1–10 µm; semiconductor features in the sub-µm to tens of µm range
