Centimeter: A Unit of Length Used in the Metric System

The centimeter (cm) is a unit of length in the metric system, which is the most widely used system of measurement in the world. The centimeter is equal to one hundredth of a meter, which is the SI base unit of length. The centimeter is also a derived unit in the International System of Units (SI), which is the official system of measurement for science and engineering. The symbol for centimeter is cm. The centimeter is used for measuring small distances and dimensions, such as the width of a fingernail or the diameter of a coin. The centimeter is also used for measuring areas and volumes, such as the area of a sheet of paper or the volume of a water bottle. The centimeter is named after the centi prefix, which means one hundredth in Latin. In this article, we will explore the definition, history, usage and conversion of the centimeter as a unit of length.

Definition of the Centimeter

The centimeter is a unit of length that is equal to one hundredth of a meter. It is defined as 1/100 meters. The meter is defined as the length of the path travelled by light in vacuum during a time interval of 1/299792458 seconds.

The definition of the centimeter has not changed since its introduction by the French Academy of Sciences in 1795, as part of the decimal metric system that was adopted after the French Revolution. However, the definition of the meter has changed several times over time, as different standards and methods of measurement were developed by various countries and organizations. The current definition of the meter as based on the speed of light was agreed upon by an international treaty in 1983.

History of the Centimeter

The origin of the centimeter as a unit of length can be traced back to 1795, when the French Academy of Sciences proposed a new system of measurement that was based on decimal fractions and natural constants. The system was called the metric system, and it was intended to replace the old and diverse systems of measurement that were used in France and other countries at that time. The metric system was designed to be simple, universal and rational.

The base unit of length in the metric system was the meter, which was defined as one ten-millionth of the distance from the equator to the North Pole along a meridian through Paris. The meter was divided into ten decimeters, each decimeter into ten centimeters, and each centimeter into ten millimeters. The prefixes deci, centi and milli indicated that they were one tenth, one hundredth and one thousandth of a meter respectively.

The metric system was officially adopted by France in 1799, and gradually spread to other countries over the next century. In 1875, an international treaty called the Metre Convention was signed by 17 countries to establish a common standard for measuring length and mass. The treaty also established an international organization called the International Bureau of Weights and Measures (BIPM) to maintain and improve the metric system.

In 1889, a new standard for the meter was created by using a platinum-iridium bar that was kept at BIPM. This bar was called the International Prototype Metre, and it was divided into ten equal parts to make standard centimeters. The bar was also compared with other national standards to ensure accuracy and consistency.

In 1960, an international conference called the General Conference on Weights and Measures (CGPM) adopted a new system of measurement called the International System of Units (SI), which was based on seven base units that could be derived from physical constants. The meter was redefined as 1,650,763.73 wavelengths of light emitted by a krypton-86 atom in a vacuum. The centimeter remained as a derived unit in SI, but it was no longer recommended for use in scientific and technical fields.

In 1983, another CGPM conference redefined the meter again as the length of the path travelled by light in vacuum during a time interval of 1/299792458 seconds. This definition was based on the speed of light, which is a universal constant that can be measured with high precision. The centimeter also changed accordingly to reflect this new definition.

Usage of the Centimeter

In this article, we will explore the definition, history, usage and conversion of the foot as a unit of length.

Definition of Foot

The foot is a unit of length that is equal to 12 inches. It is defined as 0.3048 meter by international agreement in 1959. One inch is equal to 25.4 millimeters.

The definition of the foot has changed over time, as different standards and methods of measurement were developed by various countries and organizations. The current definition of the foot as based on the meter was agreed upon by an international treaty in 1959.

History of Foot

The origin of the foot as a unit of length can be traced back to ancient times, when it was used as a measure of length based on the human body. The word foot comes from the Old English word fot, which was derived from the Proto-Germanic word fotuz. It referred to the length of a human foot, which was about 280 millimeters.

The foot was also used as a measure of length by other civilizations, such as the Romans, who used it as one-sixteenth of a Roman pace or passus. The Roman foot was about 296 millimeters.

The foot was adopted by other countries that followed the English system of measurement, such as the United States and Canada. It was also incorporated into the imperial system, which was established by an act of Parliament in 1824. The imperial system was based on seven base units that could be derived from natural and traditional units. The foot remained as a derived unit in the imperial system, but it was no longer recommended for use in scientific and technical fields.

In this article, we will explore how to convert foot to other units of length in the US customary system and the SI system. We will also provide 10 examples of conversion for each system.

How to Convert Foot to Other Units of Length in the US Customary System

The US customary system is a system of measurement that uses units such as inch, yard, mile, ounce, pound, gallon, etc. The US customary system is based on the English system of measurement that was used before the adoption of the metric system.

To convert foot to other units of length in the US customary system, we need to know the relationship between foot and other units. Here are some common units and their equivalent values in feet:

• 1 inch = 1/12 foot
• 1 yard = 3 feet
• 1 mile = 5280 feet
• 1 fathom = 6 feet
• 1 rod = 16.5 feet

To convert foot to any of these units, we need to multiply or divide by the appropriate factor. For example, to convert 10 feet to inches, we need to multiply by 12:

10 feet x 12 = 120 inches

To convert 10 feet to miles, we need to divide by 5280:

10 feet / 5280 = 0.00189 miles

To convert 10 feet to fathoms, we need to divide by 6:

10 feet / 6 = 1.667 fathoms

To convert 10 feet to rods, we need to divide by 16.5:

10 feet / 16.5 = 0.606 rods

How to Convert Foot to Other Units of Length in the SI System

The SI system (or International System of Units) is a system of measurement that uses units such as meter, kilogram, second, ampere, kelvin, mole, candela, etc. The SI system is based on the metric system that was developed in France in the late 18th century.

To convert foot to other units of length in the SI system, we need to know the relationship between foot and meter. The meter is the base unit of length in the SI system and it is defined as “the length of the path travelled by light in vacuum during a time interval of 1/299792458 seconds.” One foot is equal to 0.3048 meters.

To convert foot to any other unit of length in the SI system, we need to multiply or divide by the appropriate power of ten and add a prefix. Here are some common units and their equivalent values in meters:

• 1 kilometer = 1000 meters
• 1 centimeter = 0.01 meter
• 1 millimeter = 0.001 meter
• 1 micrometer = 0.000001 meter
• 1 nanometer = 0.000000001 meter

To convert foot to any of these units, we need to multiply by the appropriate factor and add a prefix.
