Furlong (fur) - traditional length unit
Furlong is an Imperial/US customary unit historically used in surveying and still common in horse racing. Used as one-eighth of a mile and equal to ten chains.
- Symbol: fur (also seen as f)
- System: Imperial/US customary
- Exact relations: 1 fur = 220 yd = 660 ft = 10 chains = 40 rods = 1/8 mi
- Metric equivalents: 1 fur = 201.168 m = 0.201168 km (exact)
- Typical examples: flat horse races (e.g., 5f, 6f, 7f); historical field/survey lengths
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
