A square decimeter (dm2) is a unit of area in the metric system.
It is equal to one-hundredth of a square meter (0.01 m2). The plural form is square decimeters.
The square decimeter is a practical unit for measuring things that are too big for square centimeters but too small for square meters. Think of it as a handy bridge between the two.
For example, the surface area of a small floor tile, a piece of A4 paper, or the screen of a tablet can be conveniently measured in square decimeters.
It's also frequently used in crafts like leatherwork and woodworking for measuring smaller pieces of material.
The square decimeter is also directly connected to volume—specifically, the liter.
Imagine a cube with a base of exactly one square decimeter (1 dm2) and a height of one decimeter (1 dm). The volume of this cube is one cubic decimeter (1 dm3), which is the exact definition of one liter.
This makes the square decimeter a helpful unit of measurement for visualizing the capacity of everyday items, such as a carton of milk or a water bottle.
Converting the square decimeter to other metric units is very straightforward.
Here are the most common conversions:
An are (a) is a metric unit of area, defined as 100 square meters (100 m2).
It is part of the same system as the more widely known hectare. The plural form is ares.
The hectare (ha), a much more common unit for measuring land, is derived directly from the are.
The prefix 'hecto-' means 100, so one hectare is equal to 100 ares.
Since one are is 100 square meters, a hectare is equivalent to 10,000 square meters (100 ares × 100 m2/are). This makes the hectare an ideal unit for measuring large areas, such as farms, forests, and parks.
The are was first established as part of the original French metric system in 1795. It was designed to serve as a standard base unit for measuring land, simplifying calculations required by older, traditional units.
While the hectare is more common today in agriculture and forestry, the are is still used in specific contexts, such as real estate and land registries in many countries, particularly throughout Europe.
The are serves as the foundation for other metric units of land area, making conversions straightforward. The most common related units include:
