What is a chain (US survey) unit?

It is a traditional length unit equal to 66 US survey feet, subdivided into 100 links, used historically in U.S. land surveys.

Why convert chain (US survey) to hectometers?

Converting helps translate historical survey measurements into modern metric units for accurate mapping, planning, and engineering.

Is the hectometer commonly used for measurement?

The hectometer is used for intermediate distances, especially in topographic mapping and land measurement, though metres or kilometers are more common.

Supports use in various fields including civil engineering, GIS, and agriculture

Examples

Convert 5 chain (US survey): 5 ch equals 1.0058420115 hm
Convert 10 chain (US survey): 10 ch equals 2.011684023 hm

Common Use Cases

Translating historical land survey data into metric units for modern GIS applications
Interpreting distances recorded in old U.S. property boundary descriptions
Calculating intermediate distances in civil engineering and agricultural land planning
Converting survey measurements for ease of use in metric-based mapping

Tips & Best Practices

Verify that input values are in the US survey chain unit standard prior to conversion
Use conversion outputs as approximate values due to historical unit variability
Cross-check converted results with other metric units when high precision is required
Apply converted measurements thoughtfully in surveying and planning to maintain accuracy

Limitations

The chain (US survey) is a historical, non-standard length unit which may cause minor conversion inconsistencies
Conversion accuracy varies with the exact US survey foot definition
Rounding errors may occur in the conversion process
The hectometer is an SI unit but is less common than metres or kilometers in some contexts
