About these units
Square Inch (in²)
A square inch represents the area of a one-inch by one-inch square. It is indispensable in engineering, manufacturing, machine design, and consumer product specifications. Mechanical components, gasket areas, electronic device screens, and pipe cross-sections are often measured in square inches. Because imperial units are deeply rooted in American manufacturing, the square inch enables precise communication among engineers and technicians. The unit remains important in pressure measurement as well—psi (pounds per square inch) combines force and area into one of the most widely recognized engineering units worldwide.
Square Hectometer (hm²)
A square hectometer, equal to 10,000 square meters, is equivalent to a hectare, making it a significant land unit in agriculture, forestry, and environmental planning. While the term "hectare" is far more common, hm² is technically valid within the SI framework and occasionally used in scientific or engineering reports where strict SI formatting is preferred. The unit's scale makes it ideal for measuring fields, park areas, forest plots, and moderate land parcels. Its equivalence to the hectare ensures its place in practical land measurement.
