formule

Formule is the French spelling of the word formula. The term comes from Latin forma via Old French. In English, the standard spelling is formula, though formules appear in French, Dutch, and other languages, and may occur in proper names or bilingual texts. The general sense is a concise rule, expression, or plan that prescribes how a result is obtained.

In mathematics and science, a formula is an expression that encodes a relationship or rule using symbols, numbers, and often subscripts and exponents. It can specify laws, identities, or procedures. Chemical formulas denote the composition of substances by indicating the elements and their ratios (for example, H2O for water). Formulas are central to physics, engineering, biology, and related fields, where they guide calculations and model descriptions.

In everyday and professional contexts, "formula" or "formule" can also mean a fixed recipe or composition used to produce a product, a medication, or a dish. A recipe for a cake or a pharmaceutical formulation are examples of formulations or formulas that specify ingredients and proportions to achieve a desired outcome.

In computing and office software, forms of the word appear in localized interfaces. In French-language programs, a cell or field may display a "formule" to denote a calculated value, equivalent to an English formula. The term is also used in marketing or branding to name products or programs that follow a prescribed method.

Overall, formule highlights a structured, repeatable method expressed in a symbolic or specified form, across mathematics, science, cooking, pharmacology, and technology.
