Degree: meanings, types, and common uses

Overview of the word “degree” covering academic ranks, geometric angles, polynomial order, temperature units, and other common senses and distinctions.

Author: Created: Updated:

The word "degree" denotes a level, step, or measurable amount in many fields. It can mean an educational qualification, a unit of angle or temperature, a polynomial's highest exponent, a node's connectivity in a network, or a more general measure of extent (for example, "a degree of difficulty"). Despite this variety, each sense shares the idea of placing something on a scale or marking an ordered position.

Common categories

  • Academic degrees — bachelor, master, doctorate and professional qualifications.
  • Geometric and navigational degrees — the unit of plane angle (360° in a full circle).
  • Mathematical degrees — polynomial degree; graph theory degree of a vertex.
  • Temperature degrees — degrees Celsius and Fahrenheit (note: the kelvin is used without the word "degree").
  • Other uses — scale positions in music (scale degrees), ranks, or measures of intensity.

Academic degrees are formal credentials awarded by universities and colleges. They indicate completion of a curriculum and often require coursework, examinations, or research. Common levels are undergraduate (e.g., bachelor), postgraduate (e.g., master), and doctoral (e.g., PhD). Degrees differ by country in length, naming, and professional consequences.

In mathematics and science, "degree" has precise technical meanings. A geometric degree measures angles; compasses and maps use degrees to specify direction. A polynomial's degree is the highest power with a nonzero coefficient and determines many algebraic properties. In graph theory, a vertex's degree counts incident edges and helps describe connectivity.

Other senses are widespread in everyday language and specialized fields. Temperature scales use the term for intervals, music theory names scale positions as degrees, and descriptive phrases employ degree to indicate extent. The degree symbol (°) commonly marks angular and temperature values. For further general reference on different senses and standards, see related overview.
