While the measurement units are the magnitudes that are established to determine the extent of things that are not quantifiable from the simple ‘count of individual units’, the derived units They are those that emerge from the units of measurement, and are applied for somewhat more specific magnitudes. For instance: cubic meter, pascal, volt.
A unit of measurement of length (the meter), one of mass (the kilogram), one of time (the second), one of electric current (the ampere), one of temperature (the kelvin), one of quantity of substance ( the mole), and one of light intensity (candela). From these seven it is possible to make a combination that ends up reaching any of the derived units, necessary for the measurement of another class of phenomena. Although they are not the elementary units, they are still very important intensities for humanity: without the derived units, the measurement of force, energy, pressure, power, speed or acceleration could not be possible.
As with conventional units of measure, derived units also offer the possibility of make conversions between different types. For example, it is common to use the unit of measure ‘Newton’ to measure the magnitude of the force, but there is also the unit of measure ‘Dina’, under the relation in which 1 newton equals 100,000 dynes.
The same thing happens with the measurement of energy, work and heat: there Joules are used in the scientific field, but calories are used in everyday life. The relationship is linear, insofar as a calorie is 4.181 joules.
The following list contains fifteen examples of derived units, highlighting what they come to represent, and the combination of basic units of measure that determines them.
