As you read this post, you’ll learn the origins and usage of the degree symbol and how to use it across different devices and platforms. This seemingly simple symbol contains information applicable to numerous disciplines, such as mathematics, physics, and geography.

There’s a lot to appreciate about the degree symbol, and we promise you that by the end of this read, you’ll never look at it the same way again.

Let’s get started!

Degree Symbol

The degree symbol (°) is a mathematical symbol used to denote degrees of arc in geometric measurements, such as angles, and in various scientific fields, like temperature and geographic coordinates. In Geometry, it is used to express angles; for example, a right angle is 90°. In temperature measurements, it precedes units like Celsius (°C) and Fahrenheit (°F) to indicate the temperature scale. The degree symbol helps specify measurements precisely and enhances clarity in mathematical and scientific expressions.

The degree symbol (°) is a small circle used in many contexts. It is most commonly used to represent degrees of arc (in geographical coordinates or in time measurements) or degrees of temperature. This mathematical symbol is widely used worldwide, appearing in scientific and non-scientific contexts.

Other Names

While commonly referred to as such, the degree symbol goes by a few other names in specific contexts. It may be called the “degree sign” when denoting angles in mathematics and physics. In geographical contexts, particularly when noting coordinates, it’s often known as the “degrees of arc” symbol. Furthermore, in weather reports and culinary recipes, where temperature is the key focus, it’s typically called the “degrees of temperature” symbol.

Degree Symbol Meaning

The degree symbol, denoted by a small superscript circle (°), is a powerful symbol used in various contexts to represent the concept of ‘degree.’ It serves as a unit of measurement in multiple fields. In mathematics, the degree is a plane angle measure, signifying that a circle is divided into 360 equal degrees. Thus, an angle represented as 45° is subtended by 1/8th of a circle. In geography, the degree symbol is used in the system of latitude and longitude, marking precise locations on the Earth’s surface.

Each degree of latitude or longitude represents 1/360th of the way around the globe. The degree symbol represents a relative temperature measurement measurement on a predefined scale. Whether it’s Celsius, Fahrenheit, or the historical Réaumur scale, the degree symbol denotes a specific temperature relative to the scale’s defined zero and endpoint.

This remarkable versatility of the degree symbol in representing different concepts of ‘degree’ across disciplines illustrates its broad significance in our understanding of the world.

It’s a fundamental part of maintaining consistency in digital communication and information exchange, allowing us to accurately express temperature, angle measurements, and geographical coordinates in a digital world.

ASCII Representation

ASCII Code

The basic ASCII set (which consists of 128 characters) does not have a degree symbol. The degree symbol is in the extended ASCII set, represented by the byte value 176 (B0 in hexadecimal).

Degree Symbol Uses

The degree symbol plays an integral role in various fields and disciplines. In mathematics, it’s crucial to denote angles. When you see 90°, for instance, you’ll understand that it refers to a right angle. In geography, it’s used to represent geographic coordinates, marking degrees of latitude and longitude. Perhaps most familiar to many people is its role in expressing temperature.

Both the Celsius and Fahrenheit scales use the degree symbol to denote temperatures, whether the balmy 30° of a summer day or the chilly -5° of a winter morning. Additionally, the symbol finds usage in certain scientific, engineering, and computational contexts. Its versatility is remarkable, transcending different measurement systems and fields of study.

The degree symbol (°) is widely recognized and utilized in various fields. Below are some of the primary uses of the degree symbol:

Why is the Degree Symbol Important?

The degree symbol is fundamental to our global understanding of various measures. It plays a crucial role in denoting angles in mathematics, facilitating the study of shapes, space, and the physical world. Since the degree symbol communicates coordinates, it is indispensable in navigation applications like GPS.

In weather forecasting, the degree symbol expresses temperature, helping us understand our environment, make predictions, and take necessary precautions for our health and comfort. Without the degree symbol, expressing these crucial measurements across different disciplines would be challenging and less universally understood, underscoring its importance in our daily lives and various fields of study.

Degree Symbol History

The history of the degree symbol is intrinsically tied to the history of geometry and astronomy. The concept of dividing a circle into 360 parts, or degrees, dates back to ancient times, with the Babylonians, who used a base-60 (or sexagesimal) number system as the likely originators. However, the specific symbol we recognize today as the degree symbol didn’t appear until recent centuries.

Several 16th-century scientists and mathematicians used a small raised zero (o) to denote degrees. However, in the 19th century, this became more standardized and widely adopted, ultimately evolving into the familiar circle we use today. Since then, the degree symbol has become a universally recognized sign for denoting degrees across various disciplines.

Origins of the Degree Symbol

The degree symbol’s use in temperature measurements dates back to the development of the first standardized temperature scales. One of the pioneers in this field was the Danish astronomer Ole Rømer, who, in the early 18th century, created a scale where the freezing and boiling points of water were set at 7.5 and 60 degrees, respectively. Later, in the mid-18th century, Swedish astronomer Anders Celsius proposed a more intuitive scale where the freezing point was 0 and the boiling point was 100 – the centigrade scale we know today.

These scientists used a small circle to denote ‘degrees’ of temperature, much like their contemporaries did in mathematical and geographical contexts. The Fahrenheit scale, developed by Daniel Gabriel Fahrenheit around the same time, also adopted this convention. This use of the degree symbol helped establish a standardized way of expressing temperature that is still in use worldwide today.

Evolution of the Degree Symbol

The degree symbol we recognize today has evolved significantly over centuries of use. The original symbol used to denote degrees, particularly in astronomical and mathematical contexts, was a small raised circle or zero, often seen in the works of scientists and mathematicians during the 16th century. As the usage of this symbol extended to new areas, such as temperature measurement in the 18th century, the representation became more standardized.

Over time, refinements in printing and typography contributed to the symbol’s evolution, leading to the small, superscript circle we are familiar with today. With its standard Unicode representation, this degree symbol is now universally recognized and consistently used across different languages, disciplines, and technologies, showcasing its adaptation to the changing needs of human communication and understanding.

Degree Symbol In Everyday Life

As we reflect on the degree symbol, we can appreciate its relevance and value in our daily lives. This small symbol packs a significant amount of information and facilitates communication across various topics, from the weather we experience to the precise locations we navigate to. One way to incorporate its principles into our routines is to acknowledge and appreciate its usage in various contexts consciously. When checking the weather forecast for the day, we can take a moment to recognize the degree symbol’s role in accurately conveying temperature information.

When using a map or GPS device, we can appreciate how the degree symbol helps denote exact geographical coordinates, enabling precise navigation. Doing so cultivates greater awareness and appreciation for this unsung hero of our communication and understanding. Moreover, for those interested in mathematics, physics, or other sciences, consciously understanding and using the degree symbol can help strengthen their academic foundations.
