skaleringsfaktoren

Skaleringsfaktoren, commonly translated as the scaling factor, is a numerical value used to enlarge or reduce the size of a quantity. It is the constant by which a quantity is multiplied to change its scale. In mathematics, the simple form is y = kx, where k is the scaling factor. In geometry and graphics, scaling factors can be applied to dimensions, often with separate factors for each axis (kx, ky, kz) to resize objects or images.

Applications of skaleringsfaktoren appear across disciplines. In maps and models, a scale factor converts measurements on the drawing to real-world units, for example 1:100 means a map distance is multiplied by 100 to obtain actual distance. In computer graphics and 3D modeling, scaling factors resize models while preserving or altering proportions. In statistics and data processing, scaling factors normalize or standardize data, or convert units for comparability. In physics and engineering, they relate simulated results to real systems and help express quantities in consistent units.

Properties of a scaling factor include its sign and magnitude. A positive k enlarges if k > 1 and reduces if 0 < k < 1; a negative k flips the quantity's direction as well as its size. The inverse scaling factor is 1/k (for k ≠ 0). Care is needed to maintain unit consistency when applying scaling, especially across multiple dimensions or datasets.
