Answer 1

Answer:

Firstly before knowing the conversion of Celsius and kelvin, let us understand what is kelvin.

Kelvin -

• Kelvin is the SI unit of temperature. It does not any degree sign(°) on it. What makes it genuine and standard is that it's reading ke never in negative digits like of Celsius and Fahrenheit.
• 273.16k = 0°C, where 273.16k is rounded off and taken as 273k.

Now, let's answer your question.

Question-$\sf \red {How \: to \: convert \: temperature \: to \: celcius \: scale ?}$

$\rightarrow$ Answer- To convert kelvin to Celsius, we'll use the formula given below.

• $\underline{\boxed{\sf\purple{°C=k-273}}}$

Where k=kelvin

C= celicius.

ㅤ

$\rightarrow$ $\underline{\mathcal{\green{Examples-}}}$

1)

• Convert 300k to °C-
• °C=300-273
• °C= 27°C.

2)

• Convert 473k to °C-
• °C= 473-273
• °C= 200°C.

Question - $\sf \red {How \: to \: convert \: temperature \: to \: Kelvin \: scale ?}$

$\rightarrow$ Answer- To convert Celsius to kelvin, we'll use the formula given below.

• $\underline{\boxed{\sf\purple{k=°C+273}}}$

Where k=kelvin

C=celcius

$\rightarrow$ $\underline{\mathcal{\green{Examples-}}}$

1.)

• Convert 373°C to k
• k= 373+273
• k= 646k.

2.)

• Convert 25°C to k
• k= 25+273
• k= 298k.
