What is a degree?
A degree is a unit used to measure temperatures. You can express it in °C,K or °F
The fahrenheit scale was created by Daniel Gabriel Fahrenheit in the 18th century. During his studies in Poland, he decided to create a temperature scale based on the blood temperature in the human body: he chose 98.6°F he then added more temperatures such as; the melting point of ice(32°F)and the boiling point of the water(212°F)
After The French Revolution at the end of the 18th century,a lot of countries changed their temperature scale from Fahrenheit to Celsius since it was a lot more easier. Indeed, in celsius the freezing point of water is 0°C and the boiling point of water is 100°C
Finally, Lord Kelvin invented the Kelvin scale which is now the most used temperature scale in the world
Those scales give us formules:
C=(F-32)*5/9 ; F=(C*5/9)+32
0°C=32°F 0°F=-18°C 0 K=-273°C
100°C=212°F 98.6°F=37°C
-40°C=40°F
