Final answer:
To convert a temperature from Fahrenheit to Celsius, use the formula C = (F - 32) x 5/9. To convert a temperature from Celsius to Fahrenheit, use the formula F = (C x 9/5) + 32. Therefore, 63°F is approximately equivalent to 17.22°C and 42°C is approximately equivalent to 107.6°F.
Step-by-step explanation:
To convert a temperature from Fahrenheit (°F) to Celsius (°C), you can use the formula:
C = (F - 32) x 5/9
So, if the temperature is 63°F, we can substitute it into the formula:
C = (63 - 32) x 5/9
C = 31 x 5/9
C ≈ 17.22°C
Similarly, to convert a temperature from Celsius to Fahrenheit, you can use the formula:
F = (C x 9/5) + 32
So, if the temperature is 42°C, we can substitute it into the formula:
F = (42 x 9/5) + 32
F = 378/5 + 32
F = 75.6 + 32
F ≈ 107.6°F
