This post is about a brief summary of the SI units of physical quantity and the modern metric system of measurement. A physical quantity is a quantity that can be used in the mathematical equations of science and technology. Table below is the collection for learning the most often used physical quantities together with their units and symbols. A must for everyone who deals with physics.
