Convert length and distance units — meters, feet, inches, kilometers, miles, light years and more.
| Unit | Name | Value |
|---|---|---|
| 0.001 chain | 0.066 ft | |
| 0.01 chain | 0.66 ft | |
| 0.1 chain | 6.6 ft | |
| 1 chain | 66 ft | |
| 5 chain | 330 ft | |
| 10 chain | 660 ft | |
| 50 chain | 3300 ft | |
| 100 chain | 6600 ft | |
| 1000 chain | 66000 ft |
Multiply the number of Chains by 66 to get Foots. Formula: ft = chain × 66. Example: 10 chain × 66 = 660 ft. To reverse, divide Foots by 66 to get Chains.
| Chain (chain) | Foot (ft) |
|---|---|
| 0.001 chain | 0.066 ft |
| 0.01 chain | 0.66 ft |
| 0.1 chain | 6.6 ft |
| 0.5 chain | 33 ft |
| 1 chain | 66 ft |
| 2 chain | 132 ft |
| 5 chain | 330 ft |
| 10 chain | 660 ft |
| 20 chain | 1320 ft |
| 50 chain | 3300 ft |
| 100 chain | 6600 ft |
| 250 chain | 16500 ft |
| 500 chain | 33000 ft |
| 1000 chain | 66000 ft |
| 10000 chain | 660000 ft |
To convert Chain to Foot, multiply by 66. Example: 10 chain = 660 ft
To convert Foot back to Chain, divide by 66 (multiply by 0.0151515). Use the swap button above.
Start with 100 Chains = 6600 ft as your reference point. Scale up or down from there.
The US Public Land Survey System divides land using chains and links. Surveyors routinely convert to feet for construction drawings, property descriptions, and interfacing with US engineering standards that use feet.
Old property deeds in the US, UK, Canada, and Australia describe plot dimensions in chains. Estate agents, solicitors, and land registries convert to feet for modern buyers who are unfamiliar with chains.
Original railway survey records use chains for distance (still used as the standard unit in UK rail engineering today). Converting to feet is needed for interfacing with US railway standards and cross-border projects.
Golf hole distances are traditionally measured in yards and feet in the US. Historic golf courses laid out using surveying chains (1 chain = 66 feet) require conversion when updating course maps and yardage books.
UK and Commonwealth forestry operations use chains for plot measurement in historic records. Converting to feet is needed when selling timber to US markets where foot-based lumber dimensions are standard.
Planning applications for developments on land described in chains in title deeds require conversion to feet (in the US) or meters (in the UK/metric countries) for architects' drawings and planning authority submissions.
The Chain is a unit of Length measurement (symbol: chain). 1 chain = 66 ft. Used in scientific and practical Length measurement applications.
The Foot is a unit of Length measurement (symbol: ft). It is part of an internationally recognised measurement system used alongside the Chain.
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 standard across the British Empire and is written into American law — the US Public Land Survey System still divides land using chains and links.
The foot is one of humanity's oldest measurement units, used by ancient Egyptians, Greeks, and Romans. The English statute foot was standardised at 12 inches in 1305 under King Edward I, 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 international aviation.
Common use: Chain to Foot conversion is needed when working with international standards, scientific publications, or reference materials that use different unit systems for Length measurement.
