Formula
square meters = acres × 4046.86

About Acres and Square meters
Acres (ac): An old English unit, originally the area a yoke of oxen could plow in a day; standardized at exactly 4,046.86 m² (43,560 sq ft). Common uses: Land area in the US, UK, and most former British colonies — farm sizes, residential lots, and ranch acreage.
Square meters (m²): One meter squared, the SI derived unit for area. Common uses: Real estate (apartment floor areas), gardening (planted area), solar panel coverage, room dimensions, and almost every non-US construction context.
How the conversion works
Area conversions are derived from length: 1 ft² = (0.3048 m)² = 0.092903 m². 1 acre = 4,046.86 m². 1 hectare = 10,000 m² exactly.
The exact relationship is square meters = acres × 4046.86, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.
When this conversion matters
Converting between acres and square meters comes up wherever area measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
