# 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.)
