Celsius and Fahrenheit are the two ways of measuring temperature. Both Celsius and Fahrenheit were developed by two different scientists. Celsius was developed Anders Celsius, and it was named after him in the 1700s. Fahrenheit, on the other hand, was developed by a physicist known as Daniel Gabriel Fahrenheit in 1724. When Celsius is used in measuring temperature, °C is used to denote that the temperature is measured by Celsius, the same thing is applicable to Fahrenheit when it is used in measuring the temperature, it is denoted by °F. The most commonly used measurement for temperature is Celsius.
In fact, it is mostly used in many parts of the world as the ideal measurement for temperature except for some countries. And sometimes Kelvin, which is another measurement scale for measuring temperature can be used in place of Celsius during special scientific operation. Fahrenheit, on the other hand, is used mostly in the United States. Another difference is that, when the freezing point of a substance is 32F, the equivalent in Celsius is 0°C.
