In mathematics, a **formula** is an entity constructed using the symbols and formation rules of a given logical language.

In science, a specific formula is a concise way of expressing information symbolically as in a mathematical or chemical formula.

In modern chemistry, a chemical formula is a way of expressing information about the proportions of atoms that constitute a particular chemical compound, using a single line of chemical element symbols, numbers, and sometimes other symbols, such as parentheses, brackets, and plus (+) and minus (–) signs.

The plural of *formula* can be spelled either *formulae* (like the original Latin) for mathematical or scientific senses, or *formulas* for more general senses. The informal use of the term * formula* in science refers to the general construct of a relationship between given quantities.

For example, determining the volume of a sphere requires a significant amount of integral calculus; but, having done this once, mathematicians can produce a formula to describe the volume in terms of some other parameter (the radius for example).

This particular formula is:

Having obtained this result, and knowing the radius of the sphere in question, we can quickly and easily determine its volume. Note that the quantities *V*, the volume, and *r* 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.

Expressions are distinct from formulae in that they cannot contain an equals sign; whereas formulae are comparable to sentences, expressions are more like phrases.

In a general context, formulae are applied to provide a mathematical solution for real world problems. Some may be general: **F** = *m***a**, which is one expression of Newton's second law, is applicable to a wide range of physical situations. 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.

### Famous quotes containing the word formula:

“So, if we must give a general *formula* applicable to all kinds of soul, we must describe it as the first actuality [entelechy] of a natural organized body.”

—Aristotle (384–323 B.C.)

“The *formula* for achieving a successful relationship is simple: you should treat all disasters as if they were trivialities but never treat a triviality as if it were a disaster.”

—Quentin Crisp (b. 1908)

““It’s hard enough to adjust [to the lack of control] in the beginning,” says a corporate vice president and single mother. “But then you realize that everything keeps changing, so you never regain control. I was just learning to take care of the belly-button stump, when it fell off. I had just learned to make *formula* really efficiently, when Sarah stopped using it.””

—Anne C. Weisberg (20th century)
