The majority of all mathematical study revolves around formulae in many different forms from [[quadratic equations]] to the equations of motion (mainly used in mechanical mathematics and [[physics]]). In a general context, formulae are applied to provide a mathematical problem for real world problems. Some may be general formulae designed to explain a phenomena experienced everywhere - an example is force = mass x acceleeration. It is a formula which applies anywhere in the universe. Other formulae may be specially created to solve a particular problem - for example using the equation of a [[sine curve]] to model the movement of the tides in a bay. In all cases however, formulae form the basis for all calculations. |

For other senses of this word, see formula (disambiguation).
Dalam matematik dan sains, sebuah rumus adalah cara ringkas untuk menyatakan penerangan secara bersimbol (seperti dalam sebuah rumus matematik atau kimia), atau perhubingan umum di antara perjumlahan. Salah satu rumus yang masyur adalah E=mc² Albert Einstein
(lihat special relativity).
Rumus dalam matematik
Dalam mathematics, rumus membentuk penilaian krusial pada banyak perkiraan. Contohnya masalah mendeterminasikan isi padu pada sebuah sfera adalah satu yang memerlukan beberapa jumlah integral calculus untuk menyelesainya. Walaubagaimanapun, dengan menyelesaikan ini sekali, ahli matematik boleh menghasilkan sebuah rumus untuk menjelaskan isi padu dalam segi parameter lain (jejari contohnya). Rumus terutama ini adalah:
- (the in this formula is the quantity pi).
Having determined this result, and having a sphere of which we know the radius we can quickly and easily determine the volume. Note that the quantities , the volume, and the radius are expressed as single letters. This convention, while less important in a relatively simple formula, means that mathematicians can more quickly manipulate larger and more complex formulae
In general mathematical use there is no essential difference in meaning with the term "expression", although the word "formula" tends to be reserved for an expression that "can stand on its own", that has a meaning outside of the immediate context in which it appears and a significance that can be grasped intuitively.

di mana keduanya A1 dan A2 menggambarkan "sel" (lajur A, baris 1 atau 2) dalam spreadsheet. Penilaian muncul di dalam sel mengandungi rumusnya sendiri (kumungkinan A3, di hujung nilai-nilai dalam lajur A).
Formula in manufacturing
In manufacturing, a bill of material is sometimes referred to as a formula.
