## What is temperature and Temperature Scale

Temperature is the measurement of how hot or cold the body is. Temperature is measured using thermometer.Construction of thermometers generally requires a measurable property of a substance which monotonically changes with temperature.

We have three common scale of temperature

(a) Celsius Scale: Temperature in Celsius is measured in degree.It is denoted by ° C.Melting point of ice and boiling point of water have values 0 ° C and 100° C

(b) Fahrenheit Scale : Temperature in Celsius is measured in degree but it is smaller than celsius.It is denoted by ° F.Melting point of ice and boiling point of water have values 32 ° F and 132° F

(b) kelvin Scale : Size of a degree in Celsius and kelvin scale are sam.It is denoted by K.Melting point of ice and boiling point of water have values 273.15 K and 373.15 K

__Relation Between Celsius ,Fahrenheit and Kelvin__
$\frac {C -0}{100} = \frac {F -32}{180} =\frac {K - 273}{180}$

**Example of Few questions where you can use this formula**

**Question 1**

Convert 45 ° C to Kelvin and Fahrenhiet Scale

**Solution**

We have the relation

$\frac {C -0}{100} = \frac {F -32}{180} =\frac {K - 273}{180}$

Taking $\frac {C -0}{100} = \frac {F -32}{180}$

$F= \frac {9}{5}C + 32= \frac {9}{5} \times 45 + 32= 113$ ° F

Taking $\frac {C -0}{100} =\frac {K - 273}{180}$

$K= C + 273 = 45 + 273 = 318 \ K$

**Question 2**

Convert 23 K to ° C and Fahrenhiet Scale.

**Solution**

We have the relation

$\frac {C -0}{100} = \frac {F -32}{180} =\frac {K - 273}{180}$

Taking $\frac {C -0}{100} =\frac {K - 273}{180}$

$C= K - 273= 23 - 273= -250$ ° C

Taking $\frac {C -0}{100} = \frac {F -32}{180}$

$F= \frac {9}{5}C + 32= \frac {9}{5} \times (-250) + 32= -418$ ° F

## How the Temperature Conversion calculator works

1. If Temperature in Celsius is given, Temperature in Kelvin and Fahrenhiet can be found using

$K= C + 273$

$F= \frac {9}{5}C + 32$

2. If Temperature in Kelvin is given, Temperature in Celsius and Fahrenhiet can be found using

$C= K - 273$

$F= \frac {9}{5}C + 32$

3. If Temperature in Fahrenhiet is given, Temperature in Celsius and Kelvin can be found using

$C = \frac {5(F-32)}{9}$

$K= C + 273$
