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
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
