Question

A measured temperature on Fahrenheit scale is ${200}^{\circ }F.$ What will this reading be on celsius scale ?

(a) ${40}^{\circ }C$ (b) ${94}^{\circ }C$

(c) ${93.3}^{\circ }C$ (d) ${30}^{\circ }$

Answer 1

There are three common scales to measure temperature ${}^{\circ }C$ (degree celsius), ${}^{\circ }F$ (degree fahrenhelt) and K (kelvin). The K is the SI unit.

The temperatures on two scales are related to each other by the following relationship,

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

Putting the values in above equatoin

$200-32=\frac{9}{5}{t}^{\circ }C$

$\Rightarrow \frac{9}{5}{t}^{\circ }C=168$

$\Rightarrow t^{\circ }=\frac{168\times 5}{9}={93.3}^{\circ }C$
