The word physical has a few different meanings. One, which shows up most often in lay-speak, means bodily (like a physical exam at a Dr's office or physical education in gym class in school). But that's not the meaning of the word used here. Instead, here it actually just means "of or relating to physics" or "characterized or produced by the operations of physics" or "perceptible through the senses and subject to the laws of nature." (source, Merriam Webster's dictionary)
Physical Quantities are of TWO types: 1) Fundamental Quantities. 2) Derived Quantities.
Physical quantities that need both magnitude and direction for its complete description are known as vector quantities. Physical quantities that need only direction for its complete description are known as scalar quantities.
Scalar quantities are physical quantities that can be described with a single value. They are unlike vector quantities which require both magnitude and direction.

It stands for Bill Of Quantities
Some of the basic types of physical quantities in chemistry include temperature, mass, quantity, length, and time. Some other physical quantities are amount of substance, electric current, and luminous intensity.
Physical quantities are quantities that can be measured. For example: water, distance, etc.

specific gravity
a physical quantity is an amout or any property that can be measured.
Scalar quantities - quantities that only include magnitude Vector quantities - quantities with both magnitude and direction
In Science, there are seven fundamental quantities. The seven fundamental quantities includes length, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity.
