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
Nautical mile (nmi) — unit for marine and air navigation defined exactly as 1,852 meters
Closely tied to Earth’s geometry; one minute of latitude is approximately one nautical mile. Speeds at sea and in air use knots.
- Symbols: nmi, NM
- Systems: Maritime/Aviation
- Exact relations: 1 nmi = 1,852 m = 1.852 km (exact)
- Imperial/US equivalents: 1 nmi ≈ 1.15078 mi ≈ 6,076.11549 ft
- Typical examples: charted distances; 1 knot = 1 nmi/h
