Question

In science class, Richard learns that petrol has a boiling point of 203
Fahrenheit. His teacher asks him to convert this temperature to degrees Celsius. What is the boiling point of petrol in degrees Celsius?

Answer 1

To convert from Fahrenheit to Celsius, you can use the following formula:

\[
C = \frac{5}{9} \times (F - 32)
\]

Where \( C \) is the temperature in degrees Celsius and \( F \) is the temperature in degrees Fahrenheit.

In this case, the boiling point of petrol is 203°F. Plugging in the value:

\[
C = \frac{5}{9} \times (203 - 32)
\]

Calculating inside the parentheses first:

\[
203 - 32 = 171
\]

Now, substituting this back into the equation:

\[
C = \frac{5}{9} \times 171
\]

Now multiply:

\[
C = \frac{5 \times 171}{9} = \frac{855}{9} = 95
\]

Therefore, the boiling point of petrol in degrees Celsius is **95°C**.
