Did you know!

A unit is said to be a measurement of a quantity that is explained or adopted by tradition or law. When it comes to history, different unit systems were created and used in several regions and cultures. Nowadays, the global standard of measurement is said to be as the International System of Units (SI) that is a modern form of the metric system.

Well, come to the point, before knowing about the unit converter calculator; let’s begin with some essential information of units of measurements.

International System of Units (SI Units):

The International System of Units (abbreviated SI from the French Système international d’unités), it is referred to as the international decimal system of weights and measures that derived from & extending the metric system of units. In 1960, the SI or “International System of Units” adopted by the 11th General Conference on Weights and Measures (CGPM), and it is abbreviated SI in all the languages. The SI unit conversions system is typically used in science, industry, and medicine.

Systems of Units:

The set of systems of units are:

SI (international Systems of Units) such as “meter, kilogram, second, ampere, Kelvin, mole, candela)
FPS acronym for “foot-pound-second”
MKS acronym for “meter-kilogram-second”
CGS acronym for “centimeter-gram-second”
EMU referred to as “Electromagnetic” “centimeter-gram-second-abampere”
ESU referred to as “Electrostatic” “centimeter-gram-second-abcoulom”
Atomic indicated as the “bohr-electron mass-atomic second-electron”
MTS acronym for “meter-toone-second”

The SI or International System of Units comprises the given three categories:

Base units
Supplementary units
Derived units

Let’s take a look at these categories:

Base Units:

A base unit is also said to be as a fundamental unit that is adopted for measurement of a base quantity. In this system, each unit is referred to as the dimensionally independent of the others. You can try unit conversion calculator to perform error free unit conversion. These dimensions are measurements of seven base units that are given below:

The Seven Base Units:

Length: The meter (m) referred to as the metric unit of length that is used for the measurement conversion. Experts depict that it is the distance traveled by light in a vacuum over a time interval of 1/299,792,458 of a second
Mass: The kilogram (kg) is said to be as the metric unit of mass. It originally was referred to as the mass of the liter that is one thousandth of a cubic meter. Currently, it is stated as a mass of the platinum-iridium kilogram sample, which maintained by the International des Poids et Mesures in Sevres, France
Time: The second (s) is the basic unit of time – A second (s) technically and accurate defined as the time interval equal to 9,192,631,770 periods of the radiation according to the transition between the 2 hyperfine levels of the ground state of the caesium-133 atom.
Electric current: The ampere (A) is the basic unit of an electric charge, which is passing a point in an electric circuit per unit time. 6.241×1018 electrons, or one coulomb, per second are said to be as constitutes one ampere.
Temperature: The Kelvin (K) is said to be as the basic unit of thermodynamic temperature scale. This scale is starts at 0 K and the incremental size of K is the same as that the degree of Celsius (°C). It is referred to as the triple point of water is exactly 273.16 K.
Amount of Substance: The mole (mol) is the amount of a substance that contains as many elementary entities as there are atoms in 0.012 kg of carbon-12. Remember that when the mole unit is taken into account, the entities must be specified
Luminous Intensity: The unit of luminous intensity or light is said to be as the candela (cd). Candela (cd) is said to be as the luminous intensity in a given direction of a source that emits monochromatic radiation of frequency.

Our base unit’s measurement converter helps you to perform measurement conversion between these seven base units.

Supplementary Units:

Supplementary units are said to be as the dimensionless units that are used with base units to generate derived units in the SI (International System of units), the class only contains two, purely geometrical units, they are:

Plane angle: radian (rad)
Solid angle: steradian (sr)

Radian: It is said to be as a unit of measure of angles – one radian is referred to as the angle that is made at the center of a circle by an arc for which a length is equal to the radius of the circle. Radian is taken into account for measuring plane angles, i:e 2D angles – (radian = length of Arc/radius)
Steradian: The steradian or square radian is indicated as the SI unit of solid angle that specifically used in three dimensional geometry, and it is analogous to the radian that quanitifies planar angles. Steradian is considered for measuring solid angles, i:e 3D angles – steradian = area of cross-section/(radius^2)

Now, give a read to know about the history of the Metric system:

History of the Metric System:

In 1975, the government of French officially adopted the metric system of measurement. Gabriel Mouton (a church vicar in Lyons), France, is named as the founding father of the metric system. In 1670, Gabriel did a great job as he proposed a decimal system of measurement, which the French scientists would couple of years further refining. In 1790, the National Assembly of France (French: Assemblée nationale) called for an invariable standard of measurements and weights having as its basis a unit of length that depends on the Earth’s circumference. As a convenience the system of measurements would be decimal based along with larger & smaller multiples of each unit that arrived by dividing & multiplying by 10 and its powers.
Attaining from the Greek word “metron” or a “measure” a commission assigned by the academy provided the name “meter” to the unit of length. The standard it indicated has been constructed so as to equal a fraction of the distance from the North Pole to the equator.

Because of the metric measurements adaptability to engineering and scientific work, the adoption of the system flourished with rapid expansion of the industrialized globe. In 1866, the U.S. Congress proclaimed the system lawful in commerce throughout the entire nation. Twenty years earlier, the government of French made use of the system compulsory.
From the period of 1970 to 1980, there has been as strong movement in the U.S toward the widespread use of the metric system measurement. There is a strong chance that the U.S will eventually yield to international pressure to create and label U.S. goods in the metric units of measurements. However, some of industries in the national have already converted to the metric measurement system that is now known as the SI (International System of Units).

Now, let’s take a look at the some important dates in the history of the metric system!

Important Dates In the History of The Metric System:

1670 – Gabriel Mouton proposed the decimal system of measurement that depends on a fraction of the Earth’s circumference
1671 – Jean Felix Piccard (a famous chemist) suggested the swinging pendulum as a measure of length
1790 – the National Assembly of France (French: Assemblée nationale) asked the French Academy of Sciences to develop a standard system of measures and weights
1795 – The Government of France adopted the metric measurement system
1840 – French Government hired all Frenchmen to convert measurements to the metric system
1866 – In the U.S. the congress legalized the use of the metric system of measurements. However, the use of this system was not required
1875 – The Treaty of the Meter has been signed at close of the conference of International Bureau of Weights and Measures
1957 – The United States Army and Marine Corps adopted the metric unit system. They used this system as the basis for their weapons and equipment
1965 – Great Britain began adopting the metric measurement system
1988 – The Congress passed the Omnibus Trade & Competitiveness Act that is called for all federal government agencies to utilize the metric measurement system for business by the end of 1992

British Imperial System of Measurements:

Imperial units are also named as the British Imperial System, it is said to be the units of measurement of the British Imperial System. Officially, the traditional system of measures and weights used in Great Britain from 1824 until the adoption of the metric measurements system that begun in 1965. The United States or US Customary System of measures and weights is derived from the British Imperial System of measurements. Now, imperial units are legally stated in metric terms.
