Chain - traditional surveying length unit
Chain is a historical unit used in land surveying, specifically Gunter’s chain. Used on cadastral maps and by railways and surveyors across the English-speaking world.
- 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)
League - traditional distance unit
League is a historical unit of length with region-dependent values, commonly taken as about three miles on land; a nautical league is standardized as three nautical miles. Used historically in European surveying, travel descriptions, and maritime contexts
- Symbol: none standardized
- System: Historical (European/Imperial/Maritime)
- Common relations (land): 1 league ≈ 3 statute miles ≈ 4.828 km (English/US usage); varied by country (e.g., French/Spanish leagues ranged ~4–7 km)
- Nautical league (standardized): 1 nautical league = 3 nmi = 3 × 1,852 m = 5,556 m (exact) ≈ 5.556 km
- Typical examples: literary distances (“several leagues”); maritime references (e.g., coastal limits expressed in nautical leagues)
