what is 39 celsius in fahrenheit

To convert 39 degrees Celsius to Fahrenheit, multiply by 1.8 and add 32. This gives you 102.2 degrees Fahrenheit.

Celsius was a Swedish astronomer who developed a temperature scale now named after him. He defined the freezing point of water as 0 degrees and the boiling point of water as 100 degrees. So, on the Celsius scale, water freezes at 0 degrees and boils at 100 degrees. The unit “degree Celsius” (symbol: °C) was later named in his honor.

Fahrenheit was a German physicist who developed a temperature scale now named after him. He defined the freezing point of water as 32 degrees and the boiling point of water as 212 degrees. So, on the Fahrenheit scale, water freezes at 32 degrees and boils at 212 degrees. The unit “degree Fahrenheit” (symbol: °F) was later named in his honor.

Fahrenheit is most commonly used in the United States, while Celsius is most commonly used in Europe and other parts of the world.

The United States is one of the few countries that uses Fahrenheit as its primary temperature scale. The main reason for this is that Fahrenheit was developed in the early 18th century by a German physicist named Daniel Gabriel Fahrenheit, while Celsius was developed in the late 18th century by a Swedish astronomer named Anders Celsius. Thus, Fahrenheit has been in use longer than Celsius and has been more widely adopted. Additionally, most scientific research regarding temperature is conducted using the Kelvin scale, which is based on absolute zero (the lowest possible temperature), rather than either Celsius or Fahrenheit. Therefore, scientists working in the US often use Fahrenheit when conducting research even though they may be more familiar with the Celsius or Kelvin scales.
