kWert

KWert is a term primarily used in German‑language technical and scientific literature to denote a specific coefficient or factor designated by the letter “K”. The word combines the letter with the German noun “Wert”, meaning “value”, and it functions as a generic label for a parameter that quantifies a particular property of a system, material, or process. In practice, the precise meaning of a KWert depends on the discipline in which it appears.

In engineering, a KWert often represents a correction factor applied to theoretical calculations to account for real‑world conditions such as temperature, humidity, or surface roughness. For example, in heat‑transfer analysis the KWert may modify the basic convection coefficient to reflect the influence of fouling on a heat‑exchange surface. In statistics and quality control, a KWert can be used to denote a weighting factor that adjusts the contribution of individual data points in a composite index.

The notation was popularized in the mid‑20th century as standardization of symbols became common in German technical documentation. Although the term is not a formal unit, it is widely understood among professionals who encounter it in technical manuals, standards (such as DIN or VDI), and academic publications. Similar concepts in English‑language texts are typically referred to as “K‑value”, “coefficient K” or “adjustment factor”.
