There are various scales for measuring the value of temperature of a certain object. Before we see what they are one must understand that temperature is a relative scale and only after setting a reference to zero do we measure the temperature of the object. Actually most temperature measuring devices measure only the difference in temperature. The difference between the reference (set to zero) and the object temperature.
The most common scales of measuring temperatures are the celcius, kelvin and the farenheit scales. Different schools of people follow different scales though kelvin and celcius scales are the most widely used. Now we shall look at the relationship between the three scales.
First we see celcius to farenheit formula for conversion. It goes like:
where‘F' is the temperature in farenheit and ‘C' the temperature in celcius.
The celcius to farenheit formula in plain words is “the temperature in farenheit is nine-fifth the temperature in Celcius plus thirty two”. It should be noted here that the farenheit scale is used rarely these days as a scale for measuring temperature (difference). From the formula we infer that both temperatures need not be integers simultaneously.
Now for the conversion of Celcius to Kelvin scale.
Where K is the temperature in Kelvin and as before C is the temperature in Celcius.
In plain words “the temperature in kelvin is 273.15 more than the temperature in Celcius”. The temperature in Kelvin is called the “absolute temperature”. It is the Kelvin scale that is mostly used by chemists and chemical engineers around the world.
These formulas are of importance in every field of study as all of them involve temperature measurements in some way or the other. Big factories producing various materials most often involve heat treatment processes wherein the readings may be taken using different scales by different people and when there comes a time when all measurements are to be standardized then these formulas come in handy.
In general, too it's good to know these conversions are you never know when and where they might come in handy. Say you are used to one scale of measurement in your country and when you go to another country the scale they use happens to be different, it is then that this knowledge of different scales comes to your rescue.
Above all, it is always good to have some general knowledge and knowing the celcius to farenheit formula won't take up much of your brain space.
