- For other senses of this word, see dimension (disambiguation).
In common usage, a dimension (Latin, "measured out") is a parameter or measurement required to define the characteristics of an object—i.e. length, width, and height or size and shape.
In mathematics, dimensions are the parameters required to describe the position and relevant characteristics of any object within a conceptual space —where the dimensions of a space are the total number of different parameters used for all possible objects considered in the model.
Generalizations of the concept are possible and, different fields of study will define their spaces by their own relevant dimensions, and use these spaces as frameworks upon which all other study (in that area) is based. In specialized contexts, units of measurement may sometimes be "dimensions"—meters or feet in geographical space models, or cost and price in models of a local economy.
For example, locating a point on a plane (ie. a city on a map of the Earth) requires two parameters — latitude and longitude. The corresponding space has therefore two dimensions, its dimension is two, and this space is said to be 2-dimensional (2D).
Locating the exact position of an aircraft in flight (relative to the Earth) requires another dimension (altitude), hence the position of the airplane can be rendered in a three-dimensional space (3D).
If time is added as a 3rd or 4th dimension (to a 2D or 3D space, respectively), then the airplane's estimated "speed" may be calculated from a comparison between the times associated with any two positions. For common uses, simply using "speed" (as a dimension) is a useful way of condensing (or translating) the more abstract time dimension, even if "speed" is not a dimension, but rather a calculation based on two dimensions. Adding the three Euler angles, for a total 6 dimensions, allows the current degrees of freedom —orientation and trajectory —of the airplane to be known.
