What is the Earth's equatorial radius?

It is the distance from the Earth's center to the equator along the equatorial plane, standardized at 6,378.137 kilometers according to the WGS84 reference ellipsoid.

An arpent is a historical French unit of length primarily used for measuring land, historically important in France and French colonies such as Quebec and Louisiana.

Why convert Earth's equatorial radius to arpent?

This conversion helps translate large geodetic measures into old land units useful in historical cadastral maps, legal land descriptions, and research involving French colonial territories.

Provides accurate unit transformation for geodesy, cartography, and historical land analysis.
Browser-based and user-friendly interface requiring no software installation.

Examples

1 Earth's equatorial radius equals approximately 108,988.13 arpent.
0.5 Earth's equatorial radius equals approximately 54,494.07 arpent.

Common Use Cases

Translating geodetic measurements into arpent for cadastral or legal land descriptions.
Interpreting historical land parcel dimensions from French colonial records.
Supporting geodesy and cartography applications involving legacy land unit conversions.

Tips & Best Practices

Consider regional variations of the arpent unit before applying conversion results to historical data.
Use this tool primarily for theoretical, legal, or comparative analysis rather than practical surveying.
Verify historical context when interpreting arpent values for land claims or property boundary studies.

Limitations

Arpent values varied by region and time period, so exact conversions might need contextual adjustment.
Earth's equatorial radius is a very large scale not suited for everyday surveying tasks.
Differences in historical arpent standards may affect accuracy in legal or scientific applications.
