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 Celsius
°C
Definition
The degree Celsius (°C) is a unit of temperature interval equal to one kelvin. When measuring temperature differences rather than absolute temperatures, one degree Celsius equals one kelvin, making it equivalent for interval measurements in the Celsius temperature scale.
History/Origin
Named after Anders Celsius, the degree Celsius was originally defined as 1/100 of the temperature difference between the freezing and boiling points of water. For temperature intervals, it maintains the same scale as the kelvin, providing a practical unit for everyday temperature difference measurements.
Current Use
Commonly used in everyday applications, weather reporting, and engineering for measuring temperature differences. It is widely used in HVAC systems, industrial processes, and scientific research where temperature intervals are measured in Celsius scale.
