What is the Earth's equatorial radius?

It is the distance from Earth's center to the equator along the equatorial plane, approximately 6,378.137 kilometers as standardized in the WGS84 geodetic reference.

What defines a statute league?

A statute league is a historical length unit equal to three statute miles, about 4.828 kilometers, formerly used in English-speaking countries primarily for overland and coastal distances.

Can I use this converter for precise engineering calculations?

No, because the statute league is obsolete with variable historical definitions, it is unsuitable for accurate modern engineering or navigation measurements.

Common Use Cases

Referencing historic British maps and legal land records that use leagues
Translating voyage logs or 19th-century travel distances recorded in leagues to modern terms
Analyzing historical literature and documents mentioning distance in leagues
Applying in geodesy for converting between modern geodetic measurements and historical units

Tips & Best Practices

Understand that statute league is an outdated unit and may vary regionally in historic contexts
Use this conversion tool primarily for interpretative and educational purposes
Avoid using league units for precise modern engineering or navigation calculations
Confirm unit definitions when dealing with historical records due to possible variation
Consider the fixed nature of Earth’s equatorial radius in comparison to variable historic league measures

Limitations

The statute league is obsolete and has multiple historical definitions, limiting precision
Earth’s equatorial radius is a constant, but leagues may represent approximate distances
Conversion uses standard values without accounting for localized variations of leagues
Not suitable for accurate navigation or engineering requiring exact lengths
