An acre is a U.S. customary/Imperial unit of area. The international acre equals exactly 43,560 ft2 = 4,840 yd2 = 4,046.8564224 m2 (0.40468564224 ha).
To convert acres → square meters, multiply by 4046.8564224 - to go back, divide by that factor.
A legacy "U.S. survey acre" uses survey feet and is larger by ~0.0004%-a difference negligible in ordinary real-estate or planning work.
No. One international acre equals exactly 4,046.8564224 square meters (about 0.40468564224 hectares), which is over 40 times larger than 100 m2.
A 100 m × 100 m plot has an area of 10,000 m2 (one hectare). Converting to acres: 10,000 ÷ 4,046.8564224 ≈ 2.471 acres.
An acre measures area, not length. If shaped as a square, each side would be √4,046.8564224 ≈ 63.615 meters. A classic rectangular visualization is 20.1168 m by 201.168 m (1 chain by 10 chains).
