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
Pole (also rod or perch) - traditional surveying length
Pole is a historical Imperial/US surveying unit equal to 16.5 feet. Used in land measurement, parcel descriptions, and traditional fencing
- Symbols: rd (rod), p (perch); no standard symbol for “pole”
- System: Imperial/US customary (historic surveying)
- Exact relations: 1 pole = 16.5 ft = 5.5 yd = 1/4 chain = 25 links = 1/320 mi
- Metric equivalents: 1 pole = 5.0292 m (exact)
- Typical examples: fence runs; plot dimensions in old deeds (e.g., “4 poles 3 links”)
