What is a section in land measurement?

A section is a U.S. land measurement unit equal to one square mile, commonly used in rural property delineation and legal land descriptions.

Why convert sections to square kilometers?

Converting to square kilometers helps represent land sizes in an international, standardized metric unit for broader geographic and planning applications.

Is the conversion factor fixed?

Yes, 1 section is exactly equivalent to approximately 2.5899881103 square kilometers, based on the defined unit relationships.

Use these examples to estimate land coverage in metric units from section values

Common Use Cases

Describing rural property boundaries and legal land descriptions within the U.S.
Cadastral surveying and mapping in the Public Land Survey System
Agricultural and resource management planning based on land parcels
Translating U.S. land survey data into international metric units for broader geographic application
Environmental conservation and land use studies involving large area extents

Tips & Best Practices

Verify the land parcel data is measured in sections before converting
Use the exact conversion factor of 1 section = 2.5899881103 km² for consistency
Consider possible rounding or mapping differences for legal or survey documentation
Apply this conversion to facilitate international communication of land size
Cross-check converted values with official cadastral data when used in legal contexts

Limitations

The section is specific to the U.S. land measurement system and may not be applicable internationally
Rounding and regional variations could affect precision in practical measurements
Conversion assumes exact theoretical equivalence which might not reflect real-world irregularities
