Magnitudes

We can call the magnitude of everything that can be measured, what can be observed or represented by a number. The magnitudes are studied by physics, so they have a quantitative value. The physical magnitudes are quantified using a pattern. For example, consider that the length of the pattern meter is 1.

The Physics obtained 7 magnitudes the bases is said a magnitude that is independent to the others, from this surgery the derivatives. The fundamental magnitudes are the following:

LENGTH: It is the measure of space or distance between two points. The length of an object is the distance between its ends, its linear extension measured from beginning to end.

MASS: It is the magnitude that quantifies the amount of matter in a body.

TIME: It is the physical magnitude that measures the duration or separation of events subject to change, of the systems subject to observation.

TEMPERATURE: It is a magnitude referred to the common notions of heat or cold. In general, a more "hot" object will have a higher temperature.

Luminous intensity:

CURRENT CURRENT CURRENT: The amount of electrons that passes through a section of the conductor in the unit of time is called electric current intensity.

LUMINOUS INTENSITY: In photometry, the luminous intensity is defined as the amount of luminous flux, propagating in a given direction, which emerges, crosses or impinges on a surface per unit of solid angle.

AMOUNT OF SUBSTANCE: Your unit is the mole. It arises from the need to count particles or elementary microscopic entities indirectly from macroscopic measurements (such as mass or volume). It is used to count individuals.
