omfången
Omfången, or omfången in definite form, is a Swedish term that denotes the boundary length or the overall extent of something. In geometry it refers to the length of the boundary of a two‑dimensional figure, i.e., its perimeter. For a circle, the omfången is the circumference, given by the formula C = 2πr, where r is the radius. For polygons and other closed curves, the omfången is obtained by summing the lengths of all edges along the boundary.
Beyond pure geometry, omfång can describe the general extent or reach of an object, region, or concept.
In technical usage, omkrets is another Swedish term often used for the perimeter of a circle or
