Fahrenheit (°F) and Kelvin (K) are temperature scales used in different regions and fields. While both measure temperature, they use different reference points.
Fahrenheit is a temperature scale primarily used in the United States and a few other regions.
Many people find Fahrenheit useful for describing everyday weather conditions because it provides more temperature intervals between common outdoor temperatures.
Kelvin is the SI base unit of temperature and the standard scale used across science, starting from absolute zero.
Because it starts at absolute zero, Kelvin has no negative values, which makes it ideal for scientific calculations.
