Question

Farenheit is the SI unit of temperature.

• A. Energy per unit volume
• B. Force per unit area

Answer 1

The correct option is B Force per unit area

We generally use the units like ${}^{0}C$ and ${}^{0}F$ while measuring temperature, but the SI unit of temperature is Kelvin. To express a temperature in Celcius to Kelvin, we add 273 to the obtained temperature. If the temperature is given in Farenheit, we first convert it into Celcius and then convert the obtained value to Kelvin.

To convert Farenheit to Celcius, we have :

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