What Is This Tool?
This tool allows you to convert lengths measured in chain (US survey) into meters, providing an essential resource for interpreting historical land measurements and integrating them into modern metric systems.
How to Use This Tool?
-
Enter the measurement value in chain (US survey).
-
Select the chain (US survey) unit as the 'from' unit and meter as the 'to' unit.
-
Click the convert button to view the equivalent length in meters.
Key Features
-
Converts chain (US survey) values directly into meters.
-
Based on the precise conversion rate of 1 chain (US survey) = 20.1168402337 meters.
-
Designed to assist with land surveying, cadastral mapping, and GIS applications.
-
Browser-based and easy to use with no installation required.
Examples
-
5 ch × 20.1168402337 = 100.5842011685 m
-
0.5 ch × 20.1168402337 = 10.05842011685 m
Common Use Cases
-
Interpreting distances from historical U.S. land deeds and cadastral surveys.
-
Translating legacy survey measurements for modern mapping and GIS integration.
-
Describing rural property boundaries and right-of-way distances.
-
Using metric units in construction, engineering, and laboratory settings.
Tips & Best Practices
-
Verify the origin of measurements before converting to ensure compatibility.
-
Be aware of slight differences between the US survey foot and international foot.
-
Use this tool for legacy measurements that require modern metric representation.
-
Double-check results when mixing units to maintain accuracy in documentation.
Limitations
-
Measured values may reflect historical inconsistencies due to variations in the survey foot.
-
The chain (US survey) unit is largely obsolete and may not be supported in all current measurement software.
Frequently Asked Questions
-
What is a chain (US survey)?
-
It is a traditional unit of length equal to 66 US survey feet, historically used for land surveying and subdivided into 100 links.
-
Why convert from chain (US survey) to meters?
-
To translate older land measurements into modern SI units for accurate mapping, GIS work, and legal documents.
-
Is the chain (US survey) commonly used today?
-
No, it is mostly a legacy unit used in historical contexts and may not be supported in many modern tools.
Key Terminology
-
Chain (US survey) [ch]
-
A traditional length unit equal to 66 US survey feet, used historically in U.S. land surveying and subdivided into 100 links.
-
Meter [m]
-
The SI base unit of length, defined by the distance light travels in a vacuum in 1/299,792,458 of a second.
-
US survey foot
-
A unit of length used in the US survey system, slightly different from the international foot.
