Square meters, hectares, acres — what's actually being measured?
The square meter is the SI unit of area and the basis for the metric area units above it: the hectare (10,000 m²) is used worldwide for land and farm area, and the square kilometer for large regions and countries. The acre and square mile are still standard in the US and UK for real estate, farmland and land surveying — a US football field, roughly, is about 1.32 acres, and a square mile is exactly 640 acres.
Because these units differ by several orders of magnitude — a hectare is 10,000 times a square meter, and a square mile is over 2.5 million times a square meter — small typos produce wildly wrong answers when done by hand. This converter runs the exact factors for all 6 units above so a property listing in acres, a plot given in square meters, or a region reported in square kilometers converts cleanly.
