Understanding how temperature is measured can be confusing when you are talking about Celsius, Kelvin, and Fahrenheit but once you learn the formulas for converting Celsius to Fahrenheit or the other way around, it is not all that hard.
~The classic English system of measuring temperature is called Fahrenheit. Gabriel Daniel Fahrenheit created this scale in 1724. Water freezes at 32 degrees Fahrenheit and boils at 212 degrees Fahrenheit. The difference between the freezing point and boiling point is equal to 180 degrees.
~The formula for changing Fahrenheit to Celsius is (degrees in Fahrenheit-32) x 5/9=Celsius.
~The formula for changing Celsius to Fahrenheit is (degrees in Celsius x 1.8) + 32.
~Here is a calculator from Rapid Tables. Just plug in the info and the calculator does the calculating.
~Celsius is a more modern system to measure temperature. When measuring in Celsius, the freezing point of water is 0 degrees Celsius, and the boiling point of water is 100 degrees Celsius. This may also be referred to as centigrade.
~The Kelvin method is used in most science and is based on a single point which is given a value of 0 degrees. This is called the absolute zero. This system is named for Lord Kelvin. He did a lot of work and research on temperatures. The Kelvin scale is based on energy content. For example, in the Kelvin method, water freezes at 273.15 Kelvin and boils at 373.15 Kelvin.
