About Hectare (ha)
A metric unit of area equal to 10,000 square meters (100 m × 100 m), or about 2.47 acres. Hectares are the international standard for agricultural land, forestry, national parks, and land-use statistics outside the US — European farmers, Canadian forestry, Australian ranches, and FAO global statistics all use hectares. A hectare is a convenient human-scale unit between the square meter (too small for farms) and the square kilometer (too large for individual parcels).
About Acre (ac)
An imperial unit of land area equal to 43,560 square feet (about 4,047 m² or 0.405 hectares), historically defined as the area one ox-team could plow in a day. The acre remains the standard US and UK unit for agricultural land, real estate over a certain size, forestry, ranch/farm sales, zoning, and golf-course dimensions. A US football field (including end zones) is about 1.32 acres; Central Park in New York is 843 acres.
