Step 1:: Recall the formula to convert temperature from Fahrenheit (F) to Celsius (C).
C = \frac{5}{9}(F - 32)
The formula is:
Step 2:: Plug in the value for Fahrenheit, which is 66 degrees.
C = \frac{5}{9}(66 - 32)
Step 3:: Calculate the value inside the parentheses first.
C = \frac{5}{9}(34)
Step 4:: Multiply the numbers.
C = \frac{170}{9}
Step 5:: Since the fraction $\frac{170}{9}$ is an improper fraction, convert it to a mixed number.
C = 18\frac{8}{9}
Final Answer
66 °F is equal to $18\frac{8}{9}$ °C.
