Actually, different physical quantities are measured in different ways. For example, it is quite different to measure the diameter of a table, than to measure the capacitance of a capacitor, the frequency of a sound, etc. Each one requires different methods. Even for the same quantity there might be differences, for example, low-frequency and high-frequency sounds, and ultrasounds (a frequency so high that we can't hear it), may require different methods.
The standard units used to measure the magnitude of physical quantities in physics are the International System of Units (SI units). These include units such as meters for length, kilograms for mass, seconds for time, and newtons for force.
Base quantities are fundamental physical quantities that cannot be defined in terms of other physical quantities. They are used as building blocks in expressing other physical quantities. Derived quantities, on the other hand, are physical quantities that are derived from combinations of base quantities through multiplication and division with or without other derived quantities.
Basic quantities are physical quantities that are independent and cannot be defined in terms of other physical quantities, such as length, time, and mass. Derived quantities, on the other hand, are physical quantities that are defined in terms of one or more basic quantities, such as speed, acceleration, and force.
Physical quantities can be broadly categorized as scalar or vector quantities. Scalar quantities have only magnitude, like mass or temperature, while vector quantities have both magnitude and direction, like velocity or force. Other types of physical quantities include derived quantities (obtained from combinations of base quantities) and dimensionless quantities (without units).
In physics, scale refers to the ratio between the size of an object in the real world and its representation in a measurement. It is used to accurately measure physical quantities by providing a standard reference point for comparison.

They are properties that you can measure and be verified by another party. Usually, standards are available to eliminate any difference in measurement methods and definitions. For example, we can measure length, speed, weight, humidity, temperature, and time, with certainty. Those are physical quantities. Contrarily, we cannot measure inflation rate, hunger, pain, etc. with certainty. In short they are quantities that can be measured.

Basically, anything that can be measured (or calculated on the basis of other measurements) in the world around us. All sorts of measurements can be made, for example you can measure or calculate an object's length, width, mass, weight, density, you can measure an electric current, a voltage, etc. - all of these are physical quantities.
To measure a physical quantity correctly and need to compare it with some standard quantities. Thus a standard unit is needed to measure a quantity correctly.
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.
