To convert from Square Decimeter (dm2) to Square Mile (mi2), use the following formula:
Square Mile (mi2)
=1001×10.7639×278784001× Square Decimeter (dm2)
=3.8610178489439853076×10−9× Square Decimeter (dm2)
With 10.7639 is the ratio between the base units Square Foot (ft2) and Square Meter (m2).
Let's convert 5 Square Decimeter (dm2) to Square Mile (mi2).
Using the formula:
5×3.8610178489439853076×10−9=1.9305089244719926538×10−8
Therefore, 5 Square Decimeter (dm2) is equal to 1.9305089244719926538×10−8 Square Mile (mi2).
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:
- 1 square meter (m²) = 100 square decimeters (dm²)
- 1 square decimeter (dm²) = 100 square centimeters (cm²)
A square mile (mi²), with its plural form being square miles, is an imperial unit of area equal to 27,878,400 square feet (ft²).
The "Square Mile" is the famous nickname for the City of London, the historic heart and central financial district of London, England.
This nickname comes from its compact geographical area of just 1.12 square miles (2.90 km²).
Despite its small size, it remains a global hub for finance and business, home to landmarks like the Bank of England and the London Stock Exchange.
Converting square miles to other units is essential for comparing land areas globally.
One square mile is equivalent to:
- 2.59 square kilometers (km²)
- 640 acres
- 259 hectares
This is especially useful when comparing data from countries that use the imperial system (like the United States) with those that use the metric system.
In the United States, the square mile is a fundamental unit in the Public Land Survey System (PLSS).
This system, used since 1785 to survey and sell land, is based on a grid. Here's how it works:
- Land is divided into square townships, each measuring six miles on each side.
- Each township is then divided into 36 sections.
- Each section measures exactly one square mile (or 640 acres).
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.
The imperial system is a system of measurement that was first defined in the British Weights and Measures Act of 1824. It's known for using units like inches, feet, pounds, and gallons. While most of the world now uses the metric system, the imperial system remains the official system of measurement in the United States and is still used in specific contexts in other countries, such as the United Kingdom and Canada.
