Area converter: m², hectares, acres and alqueires

Convert common metric and land-area units. Brazilian alqueire names vary by region, so this tool labels each convention and does not treat them as interchangeable legal definitions.

Examples

• 1 hectare = 10,000 m².
• 1 paulista alqueire = 24,200 m² under this tool’s stated convention.
• 1 km² = 1,000,000 m² = 100 hectares.

Regional conventions and documents

A hectare is 10,000 m². The tool uses 24,200 m² for the paulista alqueire, 48,400 m² for the mineiro/goiano alqueire and 27,225 m² for the option labelled “North alqueire”. These are the calculator’s stated regional conventions; the word alqueire alone does not establish the definition in a deed, contract or survey.

Use area units carefully

• Area is not length: a rectangle’s area requires length × width.
• The acre factor shown is rounded to 4,046.8564 m².
• For a property transaction, boundary or registration, confirm the exact unit in the official document and obtain a qualified measurement. This tool is an estimate, not a land survey.
