The equation 5(F-32)9 C5(R-32)9 C can be used to change temperatures in degrees Fahrenheit to the Celsius scalel What is the first step when converting a temperature in degrees Fahrenheit to degrees Celsius?

A) Subtract 32 from the temperature in Fahrenheit.
B) Add 32 to the temperature in Fahrenheit.
C) Multiply the temperature in Fahrenheit by 5/9.
D) Divide the temperature in Fahrenheit by 5/9.

Answer 1

The first step when converting a temperature in degrees Fahrenheit to degrees Celsius is to subtract 32 from the temperature in Fahrenheit.

Step-by-step explanation:

The first step when converting a temperature in degrees Fahrenheit to degrees Celsius is to subtract 32 from the temperature in Fahrenheit. This is because in the conversion equation 5(F-32)/9 C, the subtraction of 32 accounts for the difference between the freezing points of water on both scales. After subtracting 32, you then divide the result by 5/9 to get the temperature in degrees Celsius.
