Convert Fahrenheit to Celsius

What is a fahrenheit?

The famous physicist D. Fahrenheit was fascinated with the creation of different scientific tools. Thus, in 1709, he created the thermometer that worked with alcohols, and five years later the mercury one. Moreover, he developed a unique scale for temperature and its degree got his name – fahrenheit.

The invention was first presented in London. It contained three reference points. The zero point was measured for the mixture of equal amounts of water, ice and ammonium chloride. The second one was 32°F and corresponded to the melting of the pure ice. The third one referred to the body of a human and was initially 96°F and later changed to 98°F.

Many countries preferred this option until the second part of the 20th century. However, later European countries switched to celsius. Only in the USA, this one is still widely used and many people understand it better than other units do.

What is a celsius?

The Celsius is designated with the °C symbol and is utilized for temperature determination and measurement along with other existing options.

The story tells that Anders Celsius, the Swedish scientist, proposed to utilize 100°C as a melting point for ice and 0°C as the boiling point for water. Later, this new scale was reversed and is known and used as such until now.

The determination of these two points depends on the atmospheric pressure and can vary greatly because of its difference in regions and countries according to their sea level. That is why the standardization of the unit was a challenging process and scientists were looking for other options to replace it. Thus, kelvin was adopted as a standard unit in most regions.

Still, celsius also retains its position. It remains especially popular in meteorology and modern physics too utilizes this unit for different calculations.
