Square Metres to Acres Converter

This area converter turns square metres (m²) into acres (ac) and back, which is handy when comparing metric plot sizes against acreage used in land and property listings. Type into either field and the other side updates live.

How it works

The conversion is a single multiplication by an exact factor:

acres = m² × 0.0002471053815 and m² = acres ÷ 0.0002471053815

That factor comes from the definition of an acre as exactly 4046.8564224 square metres, so dividing 1 by 4046.8564224 gives the m²-to-acre figure. Because the factor is tiny, square-metre areas produce small acre numbers.

Example

Convert a 2000 m² plot:

2000 × 0.0002471053815 ≈ 0.4942 acres

Going the other way, 0.25 acres is 0.25 ÷ 0.0002471053815 ≈ 1011.7 m².

Square Metres (m²)	Acres (ac)
