How to convert1 square foot (sq ft) = 92903.04 square millimeter (sq mm). Square Foot (sq ft) is a unit of Area used in Standard system. Square Millimeter (sq mm) is a unit of Area used in Metric system. Square Foot: A Unit of AreaDefinition of the Square FootA 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 UnitsTo 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:
Where Square Foot is UsedThe 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:
History of Square FootThe 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. Example Conversions of Square Foot to Other UnitsHere are some examples of converting a given area in square feet to other units:
Square Millimeter: A Unit of AreaA square millimeter is a unit of area in the metric system. It is equal to the area of a square with sides that measure 1 millimeter. The symbol for square millimeter is mm2. Definition of the Square MillimeterThe square millimeter is defined as the area of a square that has a side length of 1 millimeter. This is equivalent to 0.000001 square meter, or 0.00155 square inch, or 0.00001076 square foot. The square millimeter 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 MillimeterThe square millimeter 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 millimeter was originally intended to be a unit of area equal to one hundredth of a square centimeter, or one tenmillionth of a square meter. However, due to a mistake in the definition of the meter at that time, the actual area of a square millimeter 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 platinumiridium bar kept in Paris. The square millimeter became widely used throughout the world for measuring small areas, especially in science, engineering, and medicine. It is also used in some everyday applications, such as measuring jewelry size, paper thickness, and screen resolution. How to Convert Square Millimeter to Other UnitsTo convert a square millimeter to other units of area, we can use the following conversion factors:
To convert from other units to a square millimeter, we can use the inverse of these conversion factors. For example, to convert 50 square centimeters to square millimeters, we can use: 50 square centimeters x (100 mm2 / 1 cm2) = 5000 mm2 Where Square Millimeter is UsedThe square millimeter is commonly used in many countries for measuring small areas, especially in science, engineering, and medicine. It is also used in some everyday applications, such as measuring jewelry size, paper thickness, and screen resolution. Some examples of uses of the square millimeter are:
