Link - traditional surveying length unit
Link is a historical unit used in land surveying as 1/100 of a Gunter’s chain. Used on cadastral maps, field books, and deeds throughout the English-speaking world.
- Symbols: l, lk, or lnk (varies)
- System: Imperial/US customary (historic surveying)
- Exact relations: 1 link = 1/100 chain = 1/25 rod = 0.66 ft = 7.92 in
- Metric equivalents: 1 link = 0.201168 m (exact); 100 links = 20.1168 m (1 chain)
- Typical examples: parcel frontage like “12 ch 37 lks”; old plats listing sides in chains and links
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
