Formelser

Formelser is a term found especially in Norwegian and Danish contexts, used to refer to formal expressions, formulas, or standard formulations that express a relationship, rule, or procedure. In English, the closest equivalents are formulas or formulations. The exact sense depends on the domain, but formelser generally denote compact representations that convey information efficiently.

Formelser occur across several fields. In mathematics and the sciences, they take the form of symbolic or numerical expressions such as equations, identities, or rules that compute a quantity from other quantities (for example, A = l × w, the area of a rectangle; F = m × a; H2O as the chemical formula for water). In statistics and engineering, formulas encode methods and laws, such as the mean μ = (1/n) Σ xi or the ideal gas law pV = nRT. In language and communication, formelser can refer to standard formulations, fixed phrases, or templates used to structure discourse or politeness strategies.

Formelser function as tools for precision, repeatability, and brevity. They can be learned, shared, and adapted to different contexts, and they often rely on agreed notation or terminology in a given field. They support quick calculation, clear communication, and consistent interpretation across users or practitioners.

Related concepts include formulas, formulations, and notation. The exact usage and terminology can vary by language and discipline.
