Question

A Fahrenheit thermometer registers ${110}^{\circ }F$ while a faulty Celsius thermometer registers ${44}^{\circ }C$ . Find the error in the latter

• A. ${0.667}^{\circ }C$
• B. ${0.72}^{\circ }C$
• C. ${1.2}^{\circ }C$
• D. ${7.2}^{\circ }C$

Answer 1

The correct option is A ${0.667}^{\circ }C$

The conversion formula for Fahrenheit to Celsius conversion is
$\frac{C}{5}=\frac{(F-32)}{9}$.

Using this, the ${110}^{o}F={43.33}^{\circ }C$.

So the error in the Celsius thermometer which registers ${44}^{\circ }C$ is $={0.667}^{\circ }C$.
