In 1965, the metric system was adopted but still several common units are being used in everyday life (foot, inch, mile etc). They are metre for length, kilogram for mass, second for time, ampere for electric current, kelvin for temperature, candela for luminous intensity and mole for amount of substance. All the other units are based on these units and they are called derived units. Measurement conversion charts and converters for metric, imperial and United States Customary systems.
Different systems of units are based on different choices of a set of base units. The most widely used system of units is the International System of Units, or SI (sometimes referred to as the Metric System). Please provide values below to convert inch in to centimeter cm, or vice versa.
- The Imperial system is derived from the old English units which evolved from the hundreds of Roman, Celtic and Anglo-Saxon units used in history.
- The base length unit was the metre (the definition was replaced later in 1983), the volume unit was litre (one thousandth of a cubic metre) and the unit of mass was the kilogram (mass of one litre of water).

- Plus other cooking conversions such as butter weight, and gas mark temperatures.
- Measurement is the process of determining how large or small a physical quantity is as compared to a basic reference quantity of the same kind.
A unit of measurement is a defined magnitude of a particular quantity, which is used as a standard. Any other quantity of that same kind can be expressed as a multiple of the unit of measurement.

The kilogram was originally defined as the mass of one liter of water at its freezing point in 1794, but was eventually re-defined, since measuring the mass of a volume of water was imprecise and cumbersome.

Almost all countries or cultures used different units of measurement and conversion of units within or between the same systems has become a problem. A new definition of the kilogram was introduced in 2019 based on Planck’s constant and changes to the definition of the second. Prior to the current definition, the kilogram was defined as being equal to the mass of a physical prototype, a cylinder made of a platinum-iridium alloy, which was an imperfect measure.
Metric system is a decimalized measurement system created in 1790 during the French revolution for the purpose of creating a measurement system for everybody. The base length unit was the metre (the definition was replaced later in 1983), the volume unit was litre (one thousandth of a cubic metre) and the unit of mass was the kilogram (mass of one litre of water). The kilogram and metre prototypes were kept by French government until 1875.
Convert Inch to Other Length Units
In 1875, Metre Convention (Treaty of the Metre) was signed by the 17 countries for the purpose of administering the maintenance and the development of metric standards globally. After 1875, the prototypes are kept at the office of BIPM in France. Unit Converter Online is a free service which features metric, imperial and our customary fashion.
