What is a league in length measurement?

A league is a historical unit used for land and sea distances, commonly defined as about 3 statute miles or 3 nautical miles, varying by region and period.

Why is the furlong important in US surveys?

The furlong (US survey) is a traditional unit used in older U.S. land surveys and legal documents, representing 1/8 of a US survey mile.

Can this tool be used for precise modern engineering measurements?

No, because both league and furlong are non-SI and largely obsolete, this converter is best suited for historical and legal contexts.

Tips & Best Practices

Understand the historical context of the league unit as its value varies by region and era.
Verify if the source measurement is a land league or nautical league before conversion.
Use this tool primarily for historical, legal, or academic research rather than modern engineering.

Limitations

The league’s length differs historically depending on place and time, affecting accuracy.
Neither unit is part of the SI system and is considered mostly obsolete today.
Conversion precision depends on the exact definition of the US survey foot and historical measurement variations.
