Square Foot: A Unit of Area

Definition of the Square Foot

A square foot is a unit of area that measures the size of a surface. It is defined as the area of a square whose sides are one foot long. A square foot is equal to 144 square inches, 0.092903 square meters, or 0.0000229568 acres. It is also a common unit of area in the United States customary system and the imperial system.

How to Convert Square Foot to Other Units

To convert a square foot to other units of area, we need to multiply or divide by a conversion factor. A conversion factor is a number that relates two units of measurement. For example, to convert a square foot to a square meter, we need to multiply by 0.092903, which is the conversion factor between these two units. Here are some common conversion factors for square foot and other units of area:

  • 1 square foot = 0.092903 square meters
  • 1 square foot = 144 square inches
  • 1 square foot = 0.111111 square yards
  • 1 square foot = 0.0000229568 acres
  • 1 square foot = 0.00000003587 square miles
  • 1 square foot = 929.03 square centimeters
  • 1 square foot = 92903 square millimeters

Where Square Foot is Used

The square foot is widely used in the United States, the United Kingdom, and some other countries as a standard unit of area measurement. It is used for various purposes, such as measuring the size of rooms, buildings, floors, walls, roofs, carpets, tiles, and more. Different countries may have different preferences or regulations for using the square foot or other units of area in different applications. Here are some examples:

  • In the United States, the square foot is used for measuring the floor area of residential and commercial buildings, as well as the size of carpets, tiles, and roofs.
  • In the United Kingdom, the square foot is used for measuring the floor area of residential and commercial buildings, as well as the size of carpets and tiles.
  • In Canada, the square meter is more commonly used for measuring the floor area of buildings, but the square foot is also used for some purposes, such as real estate listings and energy efficiency ratings.
  • In Australia and New Zealand, the square meter is more commonly used for measuring the floor area of buildings, but the square foot is also used for some purposes, such as real estate listings and carpet sizes.
  • In India, the square foot is used for measuring the floor area of buildings and rooms, as well as the size of carpets and tiles.
  • In China, the square meter is more commonly used for measuring the floor area of buildings and rooms, but the ping (a unit equal to 3.306 square meters) is also used for some purposes.

History of Square Foot

The concept of measuring area by using squares dates back to ancient times. The ancient Egyptians, Babylonians, Greeks, and Romans all used different units of area based on squares with different side lengths. For example, the ancient Egyptians used a unit called setat, which was equal to a square with sides of 100 cubits (about 52 meters). The ancient Greeks used a unit called plethron, which was equal to a square with sides of 100 feet (about 30 meters). The ancient Romans used a unit called iugerum, which was equal to a square with sides of 120 feet (about 35 meters).

The modern definition of the square foot was established in the late 18th century by the British Parliament as part of the imperial system. The imperial system was designed to create a uniform and consistent system of measurement based on traditional units that were widely used in Britain and its colonies. The original definition of the foot was derived from an iron rod that was kept in London as a standard measure. The original definition of the square foot was then derived from this definition as the area of a square whose sides are one foot long.

The definition of the foot has been revised several times over the years to improve its accuracy and precision. The current definition of the foot was adopted in 1959 by an international agreement as “the length equal to 0.3048 meter exactly”. The current definition of the square foot is then derived from this definition as before.

Square Decimeter: A Unit of Area

A square decimeter is a unit of area in the metric system. It is equal to the area of a square with sides of one decimeter. The symbol for square decimeter is dm2.

Definition of the Square Decimeter

The square decimeter is defined as the area of a square that has a side length of 1 decimeter, or one tenth of a meter. This is equivalent to 0.01 square meter, or 100 square centimeters, or 0.0001 square kilometer.

The square decimeter is a derived unit in the International System of Units (SI), which means that it is derived from the base unit of length, the meter. It is also a coherent unit, which means that it does not require any conversion factor when used with other SI units.

History of the Square Decimeter

The square decimeter was introduced in France in 1795 as part of the metric system, which aimed to simplify and standardize the units of measurement. The metric system was based on the decimal system, which used powers of ten to relate different units of the same quantity.

The square decimeter was originally intended to be a unit of area equal to one hundredth of a square meter, or one ten-thousandth of a square kilometer. However, due to a mistake in the definition of the meter at that time, the actual area of a square decimeter was slightly smaller than intended. This error was corrected in 1889, when the meter was redefined based on the distance between two marks on a platinum-iridium bar kept in Paris.

The square decimeter became widely used throughout the world for measuring medium-sized areas, especially in science, engineering, and medicine. It is also used in some everyday applications, such as measuring floor space, paper size, and clothing size.

How to Convert Square Decimeter to Other Units

To convert a square decimeter to other units of area, we can use the following conversion factors:

  • 1 square decimeter = 0.01 square meter
  • 1 square decimeter = 100 square centimeters
  • 1 square decimeter = 0.0001 square kilometer
  • 1 square decimeter = 15.500031 square inches
  • 1 square decimeter = 0.107639104 square feet
  • 1 square decimeter = 0.011959900 square yards

To convert from other units to a square decimeter, we can use the inverse of these conversion factors.

For example, to convert 50 square centimeters to square decimeters, we can use:

50 square centimeters x (0.01 dm2 / 1 cm2) = 0.5 dm2

Where Square Decimeter is Used

The square decimeter is commonly used in many countries for measuring medium-sized areas, especially in science, engineering, and medicine. It is also used in some everyday applications, such as measuring floor space, paper size, and clothing size.

Some examples of uses of the square decimeter are:

  • The average size of an adult human hand is about 4 dm2.
  • The standard paper size for printing documents in most countries is A4, which has an area of about 6.237 dm2.
  • The smallest unit of measurement for digital images is a pixel, which can have an area ranging from less than 0.000001 dm2 to more than 0.001 dm2 depending on the resolution and size of the screen.
  • The largest coin in circulation in the European Union is the two euro coin, which has an area of about 0.314 dm2.
  • The smallest country in the world by area, Vatican City, has an area of about 440000 dm2.

Example Conversions of Square Decimeter to Other Units

Here are some example conversions of a square decimeter to other units:

  • 1 square decimeter = 0.01 square meter
  • 1 square decimeter = 100 square centimeters
  • 1 square decimeter = 0.0001 square kilometer
  • 1 square decimeter = 15.500031 square inches
  • 1 square decimeter = 0.107639104 square feet
  • 1 square decimeter = 0.011959900 square yards
  • 1 square decimeter = 10000000000 nanometers^2
Square decimeters also can be marked as dm2.
