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”)

- Symbols: ch (common)
- System: Imperial/US customary (historic surveying)
- Exact relations: 1 chain = 66 ft = 22 yd = 4 rods = 100 links = 1/80 mile; 10 chains = 1 furlong
- Metric equivalents: 1 chain = 20.1168 m (exact)
- Typical examples: UK railway distances recorded in miles and chains; a cricket pitch length is 1 chain (22 yd)
