Convert the following degree Celsius temperature to degree Fahrenheit. a. 40°C b. 30°C

(a) Given : 

Temperature in degree Celsius =40°C 

To find : 

Temperature in degree Fahrenheit

Formula :

°F = \(\frac{9}{5}\)(°C) + 32

Calculation : 

Substituting 40°C in the formula,

°F = \(\frac{9}{5}\)(°C) + 32

= \(\frac{9}{5}\)(40) + 32

= 72 + 32

= 104°F

(b) Given : 

Temperature in degree Celsius = 30°C

To find : 

Temperature in degree Fahrenheit

Formula :

°F = \(\frac{9}{5}\)(°C) + 32

Calculation : 

Substituting 30°C in the formula,

°F = \(\frac{9}{5}\)(°C) + 32

= \(\frac{9}{5}\)(30) + 32

= 54 + 32

= 86 °F

∴ The temperature 40°C corresponds to 104°F.

The temperature 30°C corresponds to 86°F.
