Square Decimeter to Are Conversion Formula

To convert from Square Decimeter (dm2) to Are (a), use the following formula:

$\textbf{ Are} \text{ (a)}$

$= \frac{1}{100} \times \frac{1}{100}\times \textbf{ Square Decimeter} \text{ (dm2)}$

$= \frac{1}{10^{4}}\times \textbf{ Square Decimeter} \text{ (dm2)}$

$= 10^{-4}\times \textbf{ Square Decimeter} \text{ (dm2)}$

Example

Let's convert 5 Square Decimeter (dm2) to Are (a).

Using the formula:

$5 \times 10^{-4} = 0.0005$

Therefore, 5 Square Decimeter (dm2) is equal to $0.0005$ Are (a).

What is a Square Decimeter (dm²)?

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.

How Big is a Square Decimeter? Everyday Examples

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.

Square Decimeter Conversions (dm² to m² and cm²)

Converting the square decimeter to other metric units is very straightforward.

Here are the most common conversions:

1 square meter (m²) = 100 square decimeters (dm²)
1 square decimeter (dm²) = 100 square centimeters (cm²)

What is an Are (a)?

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.

From Are to Hectare: A Common Land Measurement

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 History and Modern Use of the Are

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:

Centiare (ca): Equal to one-hundredth of an are. This makes a centiare precisely one square meter (1 m²).
Decare (daa): Equal to ten ares, or 1,000 square meters (1,000 m²). The decare is often used for land measurement in parts of Eastern Europe and the Middle East.
Hectare (ha): Equal to one hundred ares, or 10,000 square meters (10,000 m²).

What is the metric system?

The metric system is a decimal-based system of measurement used by nearly every country in the world. Its key feature is the use of prefixes to denote multiples and submultiples of the base units by powers of ten.
