- The Different Temperature Measurement Scales
The Different Temperature Measurement Scales
The temperature we have available to us today, is measured by many countries using different measurement scales. The two most known around the world are Fahrenheit and Celsius, however there is a third one also, which may not be known by many.
In today’s article, we are going to talk about the different temperature scales which exist today, all around the globe. The Kelvin temperature scale is a temperature measurement scale, which was discovered by Lord Kelvin a British inventor named William Thomson.
Water is used to establish the range of the scale, by utilizing the freezing and boiling point of water. In Kelvin water freezes at 273.16 K and boils at 373 K; and the liquid, solid and vapor forms of water can be maintained simultaneously, in Kelvin. In Celsius, which is another temperature measurement scale, water freezes at zero degrees, and boils at 100 degrees Celsius.
In both scales, we can see that there is a span of 100 degrees, between the boing and freezing point of water. Which means that making an adjustment for the two different zero points on the measurement scale, can help us to easily convert Kelvins to Celsius and vice versa. The Kelvin scale can only have positive values, while the Fahrenheit and the Celsius scales, can have negative values.
Converting a temperature scale to Fahrenheit though, is not as easy; the boiling point of water is 212 degrees Fahrenheit, while the freezing point is 32. So, there is a span of 180-degree units, between the freezing point and boiling point of water.
The change in total energy that it takes to go from the freezing point to the boiling point of water is 100 degrees for Celsius and Kelvin, while for Fahrenheit is 180 degrees. When converting a degree to and from Fahrenheit to Celsius, the difference that exist between Celsius and Fahrenheit, in the freezing and boiling point of water must be taken into consideration.
When we do a conversion, we would write the change in degree, that it takes for both scales to go from the freezing to the boiling points of water as a ratio. Therefore, we would write 180/100 and we would end up with 9/5; we also need to acknowledge the fact that 32 degrees Fahrenheit, is equal to zero degrees Celsius.
If we would like to go from Fahrenheit to Celsius, then we would take the degrees in Fahrenheit and subtract 32 degrees from it, then we would multiply that result by the ratio of 9/5 we found earlier, to obtain our degrees in Celsius.
Another type of temperature measurement scale is also known as the Rankine temperature measurement Scale, which provides an absolute zero, like that of Fahrenheit. What Kelvin is for Celsius, the Rankine scale is for Fahrenheit; the Rankine temperature scale, is at 491.67 degrees, when water freezes, and it is about 671.67 degrees R when water boils.
The Rankine scale can be seen in action, in engineering systems, where degrees in Fahrenheit, are used in heat computation. Converting a temperature from one scale to the other, should not be difficult, if we know the magnitude of degree in the scale, that it takes to go from the freezing point of water, to the boiling point of water as well as the point where, for both scales water freezes.

Hi every one, I obtained a bachelor's degree in Bioinformatics back in 2006, from Claflin University, after I received my bachelor's degree, I gained full time employment as a software engineer at a Video Relay Service company, maintaining databases and developing software for a new developed device called the VPAD.
I worked at that company for two years, then I became a web developer, and worked for a magazine for three years. After that job, I worked as a Drupal web developer, as a subcontractor for the NIH, for a year and then left the job to go back to school.
