Convert Square Inch to Square Meter
Square Inch
A square inch (in²) is a unit of area commonly used in the imperial system and the U.S. customary system. It is defined as the area of a square with sides that are each 1 inch long. One square inch is equal to 1/144 of a square foot or 6.4516 square centimeters.
The square inch is derived from the inch, a unit of length that has been used for centuries. The inch was originally based on various physical objects, such as the width of a human thumb, but it was standardized in the 14th century in England. The square inch, as a unit of area, emerged as a way to measure smaller surfaces, particularly for applications such as manufacturing, fabric measurement, and printing. Today, the square inch is widely used in the United States and the United Kingdom for measuring the area of small objects, screens (such as in electronics), and materials, particularly in contexts where imperial or U.S. customary units are preferred.
Square Meter
The square meter (m²) is the SI (International System of Units) unit of area. It is defined as the area of a square with sides that are each 1 meter long. One square meter is equivalent to 1 meter × 1 meter and is used to measure areas in a variety of fields, including real estate, construction, and land measurement.
The square meter derives from the meter, which is the base unit of length in the SI system. The meter was originally defined in the late 18th century during the French Revolution as one ten-millionth of the distance from the equator to the North Pole. With the introduction of the meter, the square meter was naturally established as the unit for area. The square meter has since become the standard unit for area measurement in scientific, engineering, and everyday applications, reflecting the metric system's widespread use globally.
