C'est une forme bilinéaire, symétrique, définie positive. À deux vecteurs, elle associe un scalaire, c'est-à-dire un nombre tel que ceux qui définissent cet espace vectoriel — réel pour un espace vectoriel réel.

Le produit scalaire permet d'exploiter les notions de la géométrie euclidienne traditionnelle : longueurs, angles, orthogonalité en dimension deux et trois, mais aussi de les étendre à des espaces vectoriels réels de toute dimension, et (avec certaines modifications dans la définition) aux espaces vectoriels complexes.

In Euclidean geometry, the dot product of the Cartesian coordinates of two vectors is widely used. It is often called the inner product (or rarely projection product) of Euclidean space, even though it is not the only inner product that can be defined on Euclidean space.
