Scalar quantity
A physical quantity that has magnitude only.
A scalar quantity is a physical quantity that is fully characterized by its magnitude (or numerical value) only, and does not have any direction associated with it. Examples of scalar quantities include mass, distance, temperature, time, volume, energy, and speed. Scalar quantities can be added, subtracted, multiplied, and divided algebraically without any consideration of direction, as they are represented by a single number or value.
