Every value in this table is computed by the same conversion engine as the tool above - not typed in by hand - so the tool and the table can never disagree.

Where does the acre come from?

An acre is exactly one surveyor's chain by one furlong - 66 feet × 660 feet - which works out to 4,046.8564224 m² exactly, inherited from the same 1959 definitions as the foot itself. The hectare is simpler: 10,000 m² by definition (a 100 m square), making 1 hectare ≈ 2.47 acres. Those two units carry most of the world's land measurement between them.

Why is a square metre not 10 times a square decimetre?

The classic mistake: 1 meter is about 3.28 feet, but 1 square meter is about 10.76 square feet - the linear factor, squared. This converter also includes the regional units that trip people up in property listings: the are (100 m²), the Indian cent (1/100 acre), and the Taiwanese/Japanese ping (≈3.306 m², the area of two tatami mats). For price-per-area comparisons across listings, the property price comparator builds on this same engine.
