In everyday life, we often hear the term length, time, temperature, and weight. Apparently unconsciously we have learned about the physics discussion of "Magnitude".
However, what is the definition of this magnitude? From various sources I've read, the definition of magnitude in physics is anything that can be measured with numbers and have the exact unit.
Of the many scale as we know, the amount is divided into two principal groups: the scale and magnitude of the derivative. The definition of principal amount is the amount that has been determined in advance (on the set) based on the consensus of the physicist. In Indonesia there is a term "nine basic", in physics as well as it turns out there is a term, which is "the seven principal amount". Seven principal amount consists of scale length, time, mass, electric current, the number of molecules, and light intensity.
In addition to the amount - the amount of principal that has been stated above, is also called the derivative. The definition of the magnitude of the derivative is the amount derived from one or more of the principal amount. For example, the volume derived from the scale length; style derived from the amount of mass, length and time; velocity derived from the length and time scale. More details see table quantities and units are also at the bottom of this post.
Scale indicate the nature of the object. This trait is expressed in numbers through the measurement results. Because the magnitude scale is different from the other, then set the units for each scale. Unit also suggests that each scale is measured in different ways. In order for the uniformity, the units for scale - physical quantities based on the International System of units (SI). The SI unit is taken from the metric system has been used in France after the revolution of 1789.
Here is the scale - physical quantities and their units:
