Neliötuuma

Neliötuuma is the Finnish word for square inch. It is a unit of area in the Imperial and U.S. customary systems of measurement. One square inch is the area of a square with sides that are each one inch long.

The symbol for square inch is often written as in² or sq in. To convert square inches to other units of area, one must consider the conversion factor for length. Since there are 12 inches in a foot, one square foot is equal to 12 inches * 12 inches, which is 144 square inches. Similarly, one square meter is approximately equal to 1550 square inches.

Square inches are commonly used in various applications, particularly in countries that predominantly use the Imperial system. This includes measurements for screen sizes (like televisions and monitors), engine displacement in some automotive contexts, and even in construction and manufacturing where precise small-scale measurements are necessary. While metric units like square centimeters and square meters are more globally widespread, the square inch remains relevant in specific industries and geographical regions.
