Multiply the number of Foots by 0.0151515 to get Chains. Formula: chain = ft × 0.0151515. Example: 10 ft × 0.0151515 = 0.151515 chain. To reverse, divide Chains by 0.0151515 to get Foots.

To convert Foot to Chain, multiply by 0.0151515. Example: 10 ft = 0.151515 chain
To convert Chain back to Foot, divide by 0.0151515 (multiply by 66). Use the swap button above.
Start with 100 Foots = 1.51515 chain as your reference point. Scale up or down from there.
The US Public Land Survey System defines sections using chains and links. Surveyors converting between feet (used in construction drawings) and chains (used in legal land descriptions) perform this conversion for every property boundary survey.
British railways still officially measure track distances in miles and chains. Engineers converting from foot-based track geometry designs to chain-based distance records perform ft-to-chain conversion in every signalling and infrastructure project.
Old property deeds in the US, UK, Australia, and Canada often describe plot dimensions in chains while modern title documents use feet. Estate agents, solicitors, and surveyors convert between the two for every historic property transaction.
Golf holes are 66–550 yards = 3–25 chains. Course designers who survey in feet convert to chains for comparison with traditional golf distance records and for layout compliance with historic course specifications.
Farmers and rural valuers in Commonwealth countries encounter chain-based field measurements in historic records, converting to feet for modern machinery path planning and irrigation system design.
UK and Commonwealth forestry operations use chains for plot measurement in historic records. Converting to feet is needed for modern timber harvesting equipment specifications and forest road engineering.
The Foot is a unit of Length measurement (symbol: ft). 1 ft = 0.0151515 chain. Used in scientific and practical Length measurement applications.
The Chain is a unit of Length measurement (symbol: chain). It is part of an internationally recognised measurement system used alongside the Foot.
The foot is one of humanity's oldest measurement units, used by ancient Egyptians, Greeks, and Romans — each with slightly different values. The English statute foot was standardised at 12 inches in 1305 under King Edward I. Its definition was refined multiple times over centuries, finally fixed as exactly 0.3048 metres under the International Yard and Pound Agreement of 1959, signed by the US, UK, Canada, Australia, and South Africa. Today the foot remains official in the US, UK (for road distances and aviation), and international aviation worldwide.
Edmund Gunter invented the surveyor's chain in 1620. His design — 100 links totalling exactly 66 feet — was brilliantly chosen: 10 chains × 10 chains = 1 acre, making area calculation trivially simple in the field. 80 chains = 1 mile, 10 chains = 1 furlong. The chain became the standard survey unit across the British Empire and is written into American law — the US Public Land Survey System still divides land using chains and links.
Common use: Foot to Chain conversion is needed when working with international standards, scientific publications, or reference materials that use different unit systems for Length measurement.
