Convert square feet to hectare

Square foot

A square foot is a customary area unit equal to a square one foot on each side.

Square feet are used throughout US real estate, construction, planning, and surface measurement.

ft2 is common for lots, rooms, buildings, roofs, floor areas, campuses, and development sites.

Hectare

A hectare is a metric land-area unit equal to 10,000 square meters.

Hectares are widely used for agriculture, forestry, conservation, land administration, and planning.

ha is used for farms, forests, parks, reserves, parcels, planning zones, and managed land areas.

How to Convert Square foot to Hectare

Mathematically, hectare (ha) = square foot (ft²) converted with the formula below.

1 ft² = 0.000009 ha

1 ha = 107,639.104167 ft²

Formula: value × 0.000009290304

Example: 15 ft² = 0.000139 ha

1. Start with the source area in square feet (ft2).
2. Divide by 107,639.104167 to convert the same area into hectares (ha).
3. Keep decimals for most ft2 values, because many properties are less than one hectare.

Precision note: Use the full factor for calculations. Round hectare values based on the source ft2 precision and whether the result is for planning, listing, or broad comparison.

How many ft² in ha and ha in ft²

1 ft² = 0.000009 ha

Common Use Cases for ft² to ha

• Converting large lots, campuses, parks, or development areas from ft2 into hectares.
• Preparing metric land summaries from US square-foot property data.
• Comparing site areas with agriculture, forestry, planning, or conservation records in ha.
• Checking whether a square-foot land total has been scaled correctly into a metric land unit.
