scalar

 [ska´lar]
1. a physical quantity specified by a single number (a magnitude or point on a scale), such as mass or temperature. See also vector.
2. pertaining to a scalar quantity.

scalar

/sca·lar/ (ska´ler)
1. a quantity that has magnitude only (as opposed to also having direction), such as mass or temperature. Cf. vector.
2. pertaining to such a quantity.

scalar

describes a variable, quantity or measurement that has only magnitude (size), i.e. no directional component. Can be added arithmetically. Examples are area, speed, temperature.

scalar

in electrocardiography, a single magnitude value of a recorded electrical potential, expressed in millivolts.
