What Is This Tool?
This tool helps you convert area values from square chains, a historical imperial unit, into square hectometers, an SI-derived metric unit, making it easier to work with modern land measurement standards.
How to Use This Tool?
-
Enter the area value in square chains (ch^2).
-
Select square hectometer (hm^2) as the target unit.
-
Click convert to get the area in square hectometers.
-
Use the results for analysis or documentation purposes.
Key Features
-
Converts from square chain (ch^2) to square hectometer (hm^2).
-
Based on accurate conversion factor linking imperial and metric units.
-
Supports application in surveying, agricultural measurement, and land-use planning.
-
Browser-based and easy to use without installation.
Examples
-
5 square chains equals approximately 0.202342821 square hectometers.
-
10 square chains equals approximately 0.404685642 square hectometers.
Common Use Cases
-
Converting old land records from imperial to metric area units.
-
Measuring agricultural fields by translating square chains into hectares.
-
Supporting cadastral surveys and land-use planning where historical units are referenced.
-
Estimating areas for civil engineering or site development using consistent metric units.
Tips & Best Practices
-
Confirm the original unit is square chain before converting to avoid errors.
-
Use the tool to assist with legacy data containing imperial measurements.
-
Understand that square hectometer is equivalent to hectare for practical purposes.
-
Double-check converted values for legal or official documentation.
Limitations
-
Square chain is a historical unit with limited modern use.
-
Conversion results may be less precise for very large or fractional values due to rounding.
-
Ensure correct interpretation of original units to prevent measurement mistakes.
Frequently Asked Questions
-
What is a square chain?
-
A square chain is an imperial area unit equal to the area of a square with sides one chain (66 feet), equivalent to 4,356 square feet or 404.68564224 square meters.
-
How many square hectometers are in one square chain?
-
One square chain equals approximately 0.0404685642 square hectometers.
-
Why convert square chains to square hectometers?
-
Converting allows translating historical or imperial area measurements into metric units commonly used in agriculture, surveying, and land management.
Key Terminology
-
Square chain [ch^2]
-
An imperial area unit equal to a square with 66-foot sides; exactly one-tenth of an acre.
-
Square hectometer [hm^2]
-
An SI-derived area unit equal to a square with 100-meter sides, equivalent to one hectare.
-
Conversion rate
-
The factor used to translate one unit of area into another; here, 1 ch^2 equals 0.0404685642 hm^2.
