What are Physical Quantities? What is the first statement of the video clip?

PHYSICAL QUANTITIES: All the quantities that can be measured are called physical quantities; like mass, length, time, and temperature

But what is a physical quantity? If a quantity possess these two properties,then it is a physical quantity:

Its numerical magnitude and the unit in which it is measured.

If we say that the height of a student is 165 cm, then it is representing both the properties of a physical quantity,

i.e. 165 is the numerical magnitude while cm is the unit in which the height is measured.
