n.
1.
a. A quantity, such as mass, length, or speed, that is completely specified by its magnitude and has no direction.
b. Mathematics A number, numerical quantity, or element in a field.
2. A device that yields an output equal to the input multiplied by a constant, as in a linear amplifier.
adj.
Of or relating to a scalar.

For example, sound waves (pressure), temperature, and quantum waves are scalar quantities at each point.
Scalar systems utilize only scalar quantities such as amplitude, phase or time and generally are based upon the use of some form of antenna pattern symmetry.
Flow data continue to be displayed in three ways: as plots of a flow scalar property as it varies along a cross section of the flow field; as contour plots of either scalar quantities or the magnitudes of vector quantities throughout the flow field; and as what may be called "arrow" vector plots, which represent vector properties, usually velocities, at regular intervals across a region of the flow field.
