Question

temperature difference of 15°C on Fahrenheit scale

Answer 1

$\textbf{Answer}$

= 59°F

$\textbf{Explanation}$

Celsius Scale = °C

Fahrenheit Scale = °F

$\frac{c}{5} = \: \frac{f - 32}{9}$

Thus Celsius Scale is 15°C , we need to find it on the Fahrenheit scale.

$\frac{15}{5} = \: \frac{f - 32}{9}$

= 15 × 9/5 = F - 32

= 3 × 9 = F - 32

= 27 = F - 32

= 27 + 32 = F (by transposing)

= 59°F

Relation between Celsius and Fahrenheit scales

As the length between the two standard points is same, we can say that hundred degree celsius is equal to 180 degree fahrenheit .

Thus , 180 divisions and fahrenheit scale = 100 divisions on Celsius scale

Therefore, 1 division on fahrenheit scale = 100/180 divisions on Celsius scale

= 5/9 divisions on Celsius Scale
