The term degree is used in several scales of temperature, with the notable exception of kelvin, primary unit of temperature for engineering and the physical sciences. The degree symbol ° is usually used, followed by the initial letter of the unit; for example, "°C" for degree Celsius.

When used to represent temperature, the degree symbol (°) is used to indicate the Celsius (°C) or Fahrenheit (°F) scales. It appears immediately after the numerical value to signify the temperature measurement. For example, 25°C represents 25 degrees Celsius, and 77°F represents 77 degrees Fahrenheit.
