How to convert

1 square millimeter (sq mm) = 0.01 square centimeter (sq cm). Square Millimeter (sq mm) is a unit of Area used in Metric system. Square Centimeter (sq cm) is a unit of Area used in Metric system.

Square Millimeter: A Unit of Area

A 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 Millimeter

The 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 Millimeter

The 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 ten-millionth 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 platinum-iridium 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 Units

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

  • 1 square millimeter = 0.000001 square meter
  • 1 square millimeter = 0.01 square centimeter
  • 1 square millimeter = 0.000000001 square kilometer
  • 1 square millimeter = 0.00155 square inch
  • 1 square millimeter = 0.00001076 square foot
  • 1 square millimeter = 0.0000001196 square yard

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 Used

The 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:

  • The average diameter of a human hair is about 100 micrometers, which is equivalent to an area of about 0.008 mm2.
  • The standard paper size for printing documents in most countries is A4, which has an area of about 623700 mm2.
  • The smallest unit of measurement for digital images is a pixel, which can have an area ranging from less than 1 mm2 to more than 100 mm2 depending on the resolution and size of the screen.
  • The largest diamond ever found was the Cullinan diamond, which had an original weight of about 3106 carats and an estimated surface area of about 50000 mm2.
  • The smallest country in the world by area, Vatican City, has an area of about 44 billion mm2.

Example Conversions of Square Millimeter to Other Units

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

  • 1 square millimeter = 0.000001 square meter
  • 1 square millimeter = 0.01 square centimeter
  • 1 square millimeter = 0.000000001 square kilometer
  • 1 square millimeter = 0.00155 square inch
  • 1 square millimeter = 0.00001076 square foot
  • 1 square millimeter = 0.0000001196 square yard
  • 1 square millimeter = 1000000 nanometers^2

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.
