Navigating the World of Area Measurement
Area conversion is essential in fields ranging from real estate and architecture to agriculture and land surveying. While the metric system (square meters, hectares) is the global standard, many regions cling to traditional units that carry historical significance. This calculator bridges that gap.
Common Units Explained
- Acre (ac): A unit used in the US and UK imperial systems. Historically defined as the area of land one man could plow in one day with a team of oxen. One acre is 43,560 square feet.
- Hectare (ha): The metric standard for land planning and agriculture. One hectare equals 10,000 square meters (a square 100m on each side). It is roughly 2.47 acres.
- Tsubo (Japan): Still widely used in Japanese real estate. One tsubo is the area of two standard tatami mats (approx 3.3 square meters).
Real Estate Value Estimation
The value of land is almost never linear. While this tool provides a baseline estimate using average price-per-square-foot data from major global cities, real-world value depends on zoning, utility access, and topography. In dense urban centers like Hong Kong or New York, a single square foot can cost thousands of dollars, whereas rural farmland might cost pennies for the same area.
