So that you can immediately spot an outlandish, bogus, unreasonable result of the
measurement if that happens, and repeat the measurement. In other words, to
guard against the dreaded Curse of the Calculator . . . blindly accepting whatever
appears before you, without question, and looking foolish when you report it.
Many do. For instance, you would probably agree that your own height and weight are physical quantities. Each of these has a magnitude or size and a unit of measurement. They might be, say, 157 cm and 50 kg.
dimension
Mass refers to the amount of matter in an object, typically measured in kilograms. Magnitude, on the other hand, refers to the size or extent of something, often used in reference to the strength or intensity of a physical quantity such as force or velocity.
Length is a fundamental physical quantity that measures the distance between two points in space. It is a scalar quantity, meaning it has magnitude but no direction. Length is typically measured in meters in the International System of Units (SI).
Pressure is the physical quantity measured in bar.
Each value measured in nature has a numerical value referred to as its magnitude, which quantifies the extent or size of a physical quantity. The dimension of a measurement indicates the type of physical quantity being measured, such as length, mass, time, or temperature. Together, magnitude and dimension provide a complete description of a measurable phenomenon, allowing for comparison, analysis, and understanding of the natural world.
Each value measured in nature has a number value called its magnitude and a dimension or what is referred to as its unit of measurement. The magnitude indicates how much of a quantity is present, while the dimension specifies the type of quantity being measured, such as length, mass, time, or temperature. Together, these elements allow for a clear and standardized representation of physical phenomena.

dimension
Each value measured in nature is characterized by its magnitude and dimension. The magnitude refers to the size or quantity of the measurement, while the dimension describes the nature of the measurement, such as length, mass, or time. Together, these components provide a complete description of a physical quantity, allowing for meaningful comparisons and calculations in scientific contexts.
Each value measured in nature has a number value called its magnitude and dimension or unit of measurement. The magnitude indicates the size or extent of the quantity, while the unit provides a standard reference for that measurement, such as meters for length or kilograms for mass. Together, they allow for clear communication and comparison of physical quantities.

Such a physical quantity is a vector.
Magnitude refers to the size or intensity of something. It can be used to measure physical quantities such as length, mass, or force, as well as to describe the brightness or energy output of celestial objects like stars. In the context of earthquakes, magnitude is a measure of the energy released by the seismic event.
Because it is: * A property of physical objects * Something that can be measured (or calculated from other quantities) Hmm, it is certainly not a physical quantity that is unique to the object! Velocity is relative to some other object. Thus, the can he threw traveled at 12m/s relative to the tree but 220m/s relative to that car.
