About Chain (ch) and Foot (ft)
What is a Chain (ch)?
A chain (ch) is a surveying measurement unit traditionally used for land layout and field mapping.
1 chain = 66 feet = 22 yards
Chains were widely adopted for distance records in property mapping, directional plotting, and grid-based surveying tasks. They remain relevant due to their presence in legacy land descriptions.
What is a Foot (ft)?
A foot (ft) is a unit of linear measurement commonly used in construction, spatial planning, field engineering, and distance estimation.
1 foot = 12 inches
Feet offer practical usability for on-site measurements and layout scaling.
What Does This Converter Do?
This converter translates chains (ch) into feet (ft), connecting traditional surveying references with measurement values used in current technical, building, and mapping documents.
How to Convert Chains to Feet
To convert chains (ch) to feet (ft), use:
Feet = Chains ÷ (1 ÷ 66)
which simplifies directly to:
Feet = Chains × 66
However, since the request requires division formatting, we will present the core ratio as:
1 chain = 66 feet
1 foot = 1 ÷ 66 chain
Why Use Chains for Measurement?
Chains continue to be applied when working with:
Legacy land surveys
Archival field boundary records
Evaluation of historical plot dimensions
Research involving early land allocation layouts
Chains preserve continuity between documented land descriptions and modern spatial references.
What is One Chain in Feet?
1 chain = 66 feet
What is One Foot in Chains?
1 foot = 1 ÷ 66 chain
Approximately equal to:
1 foot ≈ 0.01515 chain
Differences Between Chains and Feet
Unit | Usage Focus | Primary Domain |
|---|---|---|

Conversion Table for Chains and Feet
All conversions use:
Feet = Chains × 66
and equivalently:
Feet = Chains ÷ (1 ÷ 66)
Chains (ch) | Conversion Formula | Equivalent in Feet (ft) | Approximate Value |
|---|---|---|---|
1 ch | 1 ÷ (1 ÷ 66) | 66 ft | 6.6 × 10¹ ft |
2 ch | 2 ÷ (1 ÷ 66) | 132 ft | 1.32 × 10² ft |
5 ch | 5 ÷ (1 ÷ 66) | 330 ft | 3.30 × 10² ft |
10 ch | 10 ÷ (1 ÷ 66) | 660 ft | 6.60 × 10² ft |
20 ch | 20 ÷ (1 ÷ 66) | 1320 ft | 1.32 × 10³ ft |
50 ch | 50 ÷ (1 ÷ 66) | 3300 ft | 3.30 × 10³ ft |
100 ch | 100 ÷ (1 ÷ 66) | 6600 ft | 6.60 × 10³ ft |
Notes
1 chain = 66 feet
1 foot = 1 ÷ 66 chain
This conversion framework supports precise interpretation of traditional surveying units within current mapping, measurement, and layout applications.
