How to convert

1 square centimeter (sq cm) = 0.01 square decimeter (sq dm). Square Centimeter (sq cm) is a unit of Area used in Metric system. Square Decimeter (sq dm) is a unit of Area used in Metric system.

Square Centimeter: A Unit of Area

A square centimeter is a unit of area in the metric system. It is equal to the area of a square with sides that measure 1 centimeter. The symbol for square centimeter is cm2.

Definition of the Square Centimeter

The square centimeter is defined as the area of a square that has a side length of 1 centimeter. This is equivalent to 0.0001 square meter, or 0.155 square inch, or 0.001076 square foot.

The square centimeter 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 Centimeter

The square centimeter 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 centimeter was originally intended to be a unit of area equal to one hundredth of a square decimeter, or one ten-thousandth of a square meter. However, due to a mistake in the definition of the meter at that time, the actual area of a square centimeter 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 centimeter 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 paper size, clothing size, and skin area.

How to Convert Square Centimeter to Other Units

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

• 1 square centimeter = 0.0001 square meter
• 1 square centimeter = 0.01 square decimeter
• 1 square centimeter = 0.000001 square kilometer
• 1 square centimeter = 0.155 square inch
• 1 square centimeter = 0.001076 square foot
• 1 square centimeter = 0.00001196 square yard

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

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

50 square inches x (6.452 cm2 / 1 sq in) = 322.6 cm2

Where Square Centimeter is Used

The square centimeter 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 paper size, clothing size, and skin area.

Some examples of uses of the square centimeter are:

• The standard paper size for printing documents in most countries is A4, which has an area of 623.7 cm2.
• The average adult human body has a skin surface area of about 18,000 cm2.
• The smallest blood cells in the human body are platelets, which have an average diameter of about 2 micrometers and an area of about 3 x 10^-6 cm2.
• The largest coin in circulation in the United States is the half dollar, which has a diameter of 3.06 cm and an area of about 7.34 cm2.
• The smallest country in the world by area, Vatican City, has an area of about 44 million cm2.

Example Conversions of Square Centimeter to Other Units

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

• 1 square centimeter = 0.0001 square meter
• 1 square centimeter = 0.01 square decimeter
• 1 square centimeter = 0.000001 square kilometer
• 1 square centimeter = 0.155 square inch
• 1 square centimeter = 0.001076 square foot
• 1 square centimeter = 0.00001196 square yard
• 1 square centimeter = 10000 micrometers^2

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.

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.
