Question

When the United States finally converts officially to metric units, the Celsius

temperature scale will replace the Fahrenheit scale for everyday use. As a

familiarization exercise, find the Celsius temperature corresponding to

a. Cool room (68°F)

b. A hot summer day (95°F) and

c. A cold winter day (5°F)

Answer 1

$$\rm{^\circ C}=\frac{5}{9}({^\circ F}-32)$$

a.

$$\rm 68{^\circ F}=\rm\frac{5}{9}(68-32)=20\rm{^\circ C}$$

b.

$$\rm 95{^\circ F}=\rm\frac{5}{9}(95-32)=35\rm{^\circ C}$$

c.

$$\rm 5{^\circ F}=\rm\frac{5}{9}(5-32)=-15\rm{^\circ C}$$
