Square Decimeters (dm²)
Definition
A square decimeter (dm²) is a metric unit of area equal to the area of a square with sides of 1 decimeter (10 cm). It equals 0.01 square meters.
History
The square decimeter is part of the original metric measurement system. While less commonly used than cm² or m², it serves as a practical intermediate unit in certain technical and educational settings.
Current use
Square decimeters are occasionally used in European countries for packaging, tile measurements, and technical specifications where square centimeters are too small and square meters are too large.
