formels

Formels is a term occasional used as the plural form of the word formel, which in several languages denotes a formula or a precise symbolic expression that represents a relationship between quantities. In standard English, the common plurals are formulas or formulae, while formels is not widely used in contemporary English technical writing. When encountered, it often reflects direct translation from a language where the equivalent plural ending is formels.

A formula, broadly defined, is a short, standardized expression that encodes how to compute or relate quantities. Formulas appear across disciplines, including mathematics, physics, chemistry, economics, and statistics. They serve to convert conceptual rules into executable calculations, and they can be symbolic, numeric, or symbolic-numeric. Examples include the area formula A = πr^2 for a circle, Newton’s second law F = ma, and the ideal gas law PV = nRT.

Notational conventions vary by field and language, but a formula typically combines variables, constants, operations, and sometimes subscripts or superscripts to denote units or specific conditions. Formulas can express static relationships, dynamic processes, or empirical correlations derived from data. A collection of formulas used within a subject area is sometimes referred to as a formula set or a formula handbook.

In usage, it is important to distinguish between a formula (a calculable rule) and a more general term such as an equation or an identity. The term formels is mainly relevant for readers encountering the word in non-English texts or in the context of language-specific terminology.
