Degree Fahrenheit
°F
Definition
The degree Fahrenheit (°F) is a unit of temperature interval equal to 5/9 of a kelvin. When measuring temperature differences, one degree Fahrenheit represents a smaller temperature change than one degree Celsius or one kelvin, making it useful for precise temperature interval measurements.
History/Origin
Named after Daniel Gabriel Fahrenheit, the degree Fahrenheit was originally defined as 1/180 of the temperature difference between the freezing and boiling points of water. For temperature intervals, it provides a finer resolution than Celsius, with 1.8°F equal to 1°C.
Current Use
Widely used in the United States for measuring temperature differences in weather, HVAC systems, and industrial processes. It is commonly used in temperature control systems where finer resolution is needed for temperature interval measurements.

Degree Centigrade
°C
Definition
The degree centigrade (°C) is an alternative name for degree Celsius, representing the same temperature interval unit. It is equal to one kelvin when measuring temperature differences and is used interchangeably with degree Celsius in many contexts.
History/Origin
The term "centigrade" was historically used to describe the temperature scale now known as Celsius. It means "hundred degrees" and refers to the 100-degree interval between the freezing and boiling points of water. For temperature intervals, it maintains the same scale as the kelvin.
Current Use
Used interchangeably with degree Celsius in many contexts, particularly in older literature and some engineering applications. It represents the same temperature interval as degree Celsius and is commonly used in temperature difference measurements.
