Mathematicians and scientists call a quantity which depends on direction a vector quantity. A quantity which does not depend on direction is called a scalar quantity. Vector quantities have two characteristics, a magnitude and a direction. Scalar quantities have only a magnitude.

The choice of which physical quantities are taken as fundamental is somewhat arbitrary, but the three usually selected are length, time, and mass.

In physics, there are seven fundamental physical quantities that are measured in base or physical fundamental units: length, mass, time, electric current temperature, amount of substance, and luminous intensity.

Two simple examples of physical quantities are the mass of an object or its temperature. We can measure both with instruments, but we can also sense them using our hands by lifting the object or touching it.

The three fundamental units are: Mass: Mass is the measure of the amount of matter in a body. The fundamental unit of mass is Kilogram . Time: Time is a measurable period. The basic fundamental unit of time is second . Length: The length of an object is the distance between the two ends of an object.

Magnitude (how much) and multitude (how many), the two principal types of quantities, are further divided as mathematical and physical. In formal terms, quantities?their ratios, proportions, order and formal relationships of equality and inequality?are studied by mathematics.

Scalar, a physical quantity that is completely described by its magnitude. Examples of scalars are volume, density, speed, energy, mass, and time.

Examples: volume, mass, length, people, number, (x + y), area, etc. We refer to quantity in many day-to-day situations.
