# You measure the temperature of a substance in a chemistry lab at 32°F. What is the temperature in degrees Celsius?

${0}^{\circ}$C

#### Explanation:

The conversion from Fahrenheit to Celsius is given below by any one of the equations:

T(°C) = (T(°F) - 32) × 5/9
or
T(°C) = (T(°F) - 32) / (9/5)
or
T(°C) = (T(°F) - 32) / 1.8

A few common ones are:

${0}^{\circ} C = {32}^{\circ} F$
${100}^{\circ} C = {212}^{\circ} F$
$- {40}^{\circ} C = - {40}^{\circ} F$

The temperature is ${0}^{o} C$

#### Explanation:

The freezing point of water in ${F}^{o}$is 32 The freezing point of water in ${C}^{o}$ is 0

The boiling point of water in ${F}^{o}$ is 212 ${F}^{o}$ There is a difference of 180 ${F}^{o}$

The boiling point of water in ${C}^{o}$ is 100 ${C}^{o}$ There is a difference of 100 ${C}^{o}$

This makes for a ratio of $180 {F}^{o} / 100 {C}^{o}$ or $9 {F}^{o} / 5 {C}^{o}$

To Convert from degrees F to degree C. Subtract 32 the difference between the starting points of F and C. Then multiple by the ratio of
$5 {C}^{o} / 9 {F}^{o}$

so $32 - 32 \times \frac{5}{9}$ = 0 ${C}^{o}$
