Square Meter: A Unit of Area

Definition of the Square Meter

A square meter 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 meter long. A square meter is equal to 10,000 square centimeters, 1,000,000 square millimeters, or 0.0001 hectares. It is also the base unit of area in the International System of Units (SI).

How to Convert Square Meter to Other Units

To convert a square meter 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 meter to a square foot, we need to multiply by 10.7639, which is the conversion factor between these two units. Here are some common conversion factors for square meter and other units of area:

• 1 square meter = 10.7639 square feet
• 1 square meter = 1.19599 square yards
• 1 square meter = 0.000247105 acres
• 1 square meter = 0.0000386103 square miles
• 1 square meter = 10000 square centimeters
• 1 square meter = 1000000 square millimeters

Where Square Meter is Used

The square meter is widely used around the world as a standard unit of area measurement. It is used for various purposes, such as measuring the size of rooms, buildings, plots of land, maps, carpets, paintings, and more. Different countries may have different preferences or regulations for using the square meter or other units of area in different applications. Here are some examples:

• In most countries, the square meter is used for measuring the floor area of residential and commercial buildings.
• In the United States, the square foot is more commonly used for measuring the floor area of buildings, but the square meter is also used for some purposes, such as energy efficiency ratings and environmental impact assessments.
• In Canada, the square meter is used for measuring the floor area of buildings, but the acre is also used for measuring the size of land parcels.
• In Australia and New Zealand, the square meter is used for measuring the floor area of buildings and the size of land parcels, but the hectare is also used for measuring large areas of land.
• In India, the square meter is used for measuring the floor area of buildings and the size of land parcels, but the bigha and the acre are also used for measuring agricultural land.
• In China, the square meter is used for measuring the floor area of buildings and the size of land parcels, but the mu and the hectare are also used for measuring agricultural land.

History of Square Meter

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 meter was established in 1795 by the French Academy of Sciences as part of the metric system. The metric system was designed to create a universal and rational system of measurement based on natural phenomena and decimal multiples. The original definition of the meter was one ten-millionth of the distance from the equator to the North Pole along a meridian. The original definition of the square meter was then derived from this definition as the area of a square whose sides are one meter long.

The definition of the meter has been revised several times over the years to improve its accuracy and precision. The current definition of the meter was adopted in 1983 by the General Conference on Weights and Measures as “the length of the path travelled by light in vacuum during a time interval of 1/299792458 second”. The current definition of the square meter is then derived from this definition as before.

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 mile 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 mile was derived from an ancient Roman unit called mille passus (thousand paces), which was equal to about 5000 feet or 1480 meters. The original definition of the square mile was then derived from this definition as the area of a square whose sides are one mile long.

The definition of the mile has been revised several times over the years to improve its accuracy and precision. The current definition of the mile was adopted in 1959 by an international agreement as “the length equal to 1609.344 meters exactly”. The current definition of the square mile is then derived from this definition as before.
