Conversion of Temperature
Pratik is having a phone conversation with his uncle who is living in US.
He was telling that the day is sunny and the temperature is 76 degree fahrenheit.
But in the wether news on television, you heard that the temperature is measured in degree celsius.
And then he asked to his father who told his that the temperature is measured on different scales.
And these scales can be converted from one to another. Like, the 76 degree fahrenheit will be 25 degree celsius.
And, it is similar to the conversion of weights and conversion of distances.
Let's convert the temperature from one scale to another scale.
Now, we want to convert degree Celsius to kelvin and vice versa.
Suppose we convert
$T°C$
into kelvin scale so, we add
$273$
into it.
So,
$T°C$
can be converted into kelvin scale as,
Similarly, we can convert kelvin into
$°C$
as,
Now, we can write this conversion of temperature as,
Suppose we have to convert temperature from degree Celsius scale to degree Fahrenheit scale and vice versa.
So, we can convert them as,
And, with the help of these conversions we can convert the temperature from
$°F$
to Kelvin as,
Now, let's understand this with the help of some examples.
Suppose we have to convert
$113°F$
to kelvin.
So, first we convert it into
$°C$
as,
Then, we have the value of
$113°F$
in the Celsius scale as,
Now, if we add
$273$
then, we have this temperature in kelvin scale.
So, we have the conversion of
$113°F$
to kelvin.
Suppose we have to convert
$313K$
into
$°F$
.
So, first we convert this Kelvin scale into Celsius scale as,
Then, we convert this Celsius to Fahrenheit as,
So, we have the conversion of
$313K$
to
$°F$
.
Revision
We can convert the temperature from one scale to another scale as,
