Scalar quantity
From Conservapedia
(Redirected from Scalar)
A scalar quantity is a measurement that does not contain directional information,[1] but only magnitude.[2] It is opposed to a vector quantity, which contains both magnitude and direction.
Every real number is a scalar, because it contains only magnitude. Scalar quantities also exist in the real world, such as temperature. (Note, however, that the change in temperature is a vector.)
