In the quaternion analysis, a quantity that has magnitude, but not direction; -- distinguished from a vector, which has both magnitude and direction.
A quantity that possesses a magnitude but not a direction. Mass and length are common examples.
A scalar is an element of the field of scalars for a vector space. The specification of a vector space includes specifying a field of scalars. The rules of scalar multiplication for that vector space apply to scalars from that field. Examples: R3 has real numbers for scalars C has complex numbers for scalars when viewed as a vector space over the complexes, but it can also be defined as a vector space with real scalars (a vector space "over the reals") in which case a basis would be {1,}.

a physical quantity that can be completely specified by its magnitude alone
In science, a physical quantity with magnitude but no direction. The analogy in Trans-Biological Kinesis is an idea or human effort with force but no direction. Compare: Vector.
A program with no Vector instructions -- cf Sequential
a quantity with magnitude but without direction; expressed as a simple number.
a physical quantity which can be specified by a single numerical value, including the unit. (Strictly the value must be the same in all reference frames or coordinate systems that are not moving relative to one another.) Most electrical quantities including charge, potential and emf, are scalars. Electric field and magnetic filed are not scalars - they are vector quantities.
A quantity that is defined by its magnitude only (ie energy, temperature).
A quantity that has no direction in space, only an amount. Cf. vector.
a variable quantity that cannot be resolved into components
of or relating to a directionless magnitude; "scalar implicatures"
a coordinate whereas a vector can be described by coordinates, but it is not the collection of its coordinates
a number with no vector direction, like speed
a physical quantity whose definition does not in any way depend on direction in space
a quantity described by its value or size, and possibly by a unit
a quantity which has magnitude (numerical size) only
a regular number that only represents a single value (where a vector represents two values)
a single number, as opposed to a vector, which has three numbers associated with it
a tensor of rank zero, and a vector is a tensor of rank one
a vector characterized by magnitude and time
A physical quantity that involves magnitude, but not direction. Examples are speed, temperature, and pressure. Quantities that also involve direction, such as velocity, are called vectors.
Of or pertaining to magnitude but not phase.
A scalar is a quantity that has magnitude only. Measuring Distance
(1) A quantity characterized by a single number. (A) (I) (2) Contrast with vector.
A quantity, like distance, which has only a magnitude or size. Quantities which are not scalar are knon as vector quantities.
a quantity that only has a magnitude, and is represented by a single number, such as time and mass.
A scalar is a number (a magnitude) without a direction (compare with vector). For example, speed is a scalar; it tells you how fast something is traveling but not the direction.
Mathematical description of a physical quantity, consisting only of a value, as opposed to a vector.
A quantity that can be completely specified by a number and unit and therefore has magnitude only.
A quantity that has a magnitude but no direction. Speed is an example of a scalar quantity.
Any physical quantity whose field can be described by a single numerical value at each point in space. A scalar quantity is distinguished from a vector quantity by the fact that a scalar quantity possesses only magnitude, whereas a vector quantity possesses both magnitude and direction.
A single number, as opposed to a multidimensional vector or matrix.
In physics, a scalar is a simple physical quantity that does not depend on direction, and therefore does not depend on the choice of a coordinate system.
