What Is This Tool?
This tool allows users to convert lengths from foot (ft), a common unit in imperial and U.S. customary systems, to chain (US survey) (ch), a traditional surveying unit historically used in U.S. land measurements.
How to Use This Tool?
-
Enter the length value in feet (ft) you want to convert.
-
Select foot (ft) as the starting unit and chain (US survey) (ch) as the target unit.
-
Click the convert button to see the equivalent length in chains.
-
Use the provided examples as a guide to confirm your conversions.
Key Features
-
Supports conversion between foot and chain (US survey) units.
-
Provides clear unit definitions and historical context.
-
Includes practical examples for straightforward conversions.
-
Browser-based and easy to use for surveyors, engineers, and property professionals.
Examples
-
Convert 10 ft to chain (US survey): 10 × 0.0151514848 = 0.151514848 ch.
-
Convert 100 ft to chain (US survey): 100 × 0.0151514848 = 1.51514848 ch.
Common Use Cases
-
Reconciling current measurements with historical U.S. land survey records and cadastral data.
-
Converting legacy survey data to modern measurement units for mapping and GIS applications.
-
Describing linear distances in rural property boundary and right-of-way surveys.
Tips & Best Practices
-
Be aware that the US survey foot differs slightly from the international foot, important in precise surveys.
-
Use this conversion carefully when interpreting historical land documents to maintain accuracy.
-
Verify that conversions follow local measurement standards and historical contexts.
Limitations
-
US survey foot and international foot are not identical, affecting precision.
-
Chain (US survey) is a legacy unit that may be unfamiliar to many modern users.
-
Conversions require respecting local standards and historical measurement contexts to prevent errors.
Frequently Asked Questions
-
What is the foot (ft) unit used for?
-
The foot is a length unit used in imperial and U.S. customary systems for everyday measurements, construction, aviation altitudes, and topographic elevations.
-
What is the chain (US survey) unit?
-
The chain (US survey) is a traditional length unit equal to 66 US survey feet, historically used in U.S. land surveying and cadastral work.
-
Why convert foot to chain (US survey)?
-
Conversion helps reconcile modern lengths with historical land survey records and improves accuracy in mapping and property boundary descriptions.
