How do I convert square feet to square meters?

Multiply square feet by 0.0929 (or divide by 10.7639) to get square meters. For example, 1,000 sq ft equals about 92.9 m². The exact conversion factor is 0.09290304 because 1 foot equals exactly 0.3048 meters.

How many square feet are in an acre?

One acre equals 43,560 square feet. A half-acre is 21,780 sq ft, a quarter-acre is 10,890 sq ft. The acre is an imperial unit historically defined as the area one ox could plow in a day.

How do I convert acres to hectares?

One acre equals about 0.4047 hectares. To convert acres to hectares, multiply by 0.4047. To go the other way, multiply hectares by 2.4711. A 10-acre property is about 4.05 hectares.

What is the difference between a square yard and a square meter?

A square yard is 9 square feet, or about 0.8361 square meters. A square meter is slightly larger at 1.196 square yards. Square yards remain common in US carpet pricing; square meters are the global standard.

Why isn't there a "square mile" option?

Square miles are typically used for very large geographic areas (640 acres = 1 sq mile = about 2.59 km²). For consumer use cases — homes, lots, lawns, fields — square feet through hectares cover the practical range. Use a dedicated geographic converter for square miles.

Are these conversion factors exact?

The square foot to square meter conversion (0.09290304) is exact by definition, because the international foot is exactly 0.3048 meters. The acre to square meter conversion (4046.8564) is also exact. Other conversions follow from these definitions.

Why Different Area Units?

Square Feet (sq ft)

The standard US unit for interior space, real estate listings, and construction materials. 1 sq ft = 144 sq in.

Square Meters (m²)

The SI unit, used worldwide except in the US. Standard for international real estate, scientific measurement, and product specifications.

Square Yards (sq yd)

Common for carpet pricing in the US. 1 sq yd = 9 sq ft. Sometimes called "yardage."

Acres

US imperial unit for land area. 1 acre = 43,560 sq ft. Historically the area one ox could plow in a day; still standard for US real estate lots.

Hectares (ha)

Metric unit for land. 1 ha = 10,000 m² ≈ 2.471 acres. Standard in agriculture, forestry, and international real estate.

Square Miles

For very large areas: 1 sq mi = 640 acres ≈ 2.59 km². Used for cities, counties, and large land tracts but not consumer projects.
