Area conversions are vital for real estate, agriculture, landscaping, flooring, and construction. They scale as the square of length units, which is why the numbers can seem surprisingly large or small at first glance.

Understanding Square Kilometers and Hectares

Square meters and square feet are the everyday units for rooms, homes, and building plots. Acres and hectares measure land — an acre (about 4,047 m²) is the traditional measure in the US and UK, while a hectare (10,000 m²) is the metric standard used worldwide for farmland. One hectare equals about 2.47 acres, a ratio worth memorizing for anyone working with land.

How accurate is this conversion?

Because area is length squared, the conversion factors are the square of the corresponding length factors. For example, since 1 foot = 0.3048 meters exactly, 1 square foot = 0.3048² = 0.09290304 square meters exactly.

All conversion factors on ClearUnits are based on internationally recognised standards (the International System of Units, SI, and official definitions). Factors are reviewed for accuracy and the calculator uses full-precision values, rounding only the displayed result.
