66° F to C: Converting 66° Fahrenheit to Celsius
Methods
Converting 66° F to C Mathematically
There is a specific formula to use when converting 66° Celsius to Fahrenheit:
C
=
(
F
−
32
)
×
5
9
C = (F - 32) × \frac{5}{9}
C = ( F − 32 ) × 9 5
So, to convert 66° F to C, we will want to insert the Fahrenheit value into the equation:
C
=
(
66
−
32
)
×
5
9
C = (66 - 32) × \frac{5}{9}
C = ( 66 − 32 ) × 9 5
Then we can solve the equation:
C
=
34
×
5
9
C = 34 × \frac{5}{9}
C = 34 × 9 5
C
=
34
×
5
9
=
18.889
C = 34 × \frac{5}{9} = 18.889
C = 34 × 9 5 = 18.889
(If the decimal is really long, we can round to the nearest three decimal places.)
C
=
18.889
C = 18.889
C = 18.889
So:
66° Fahrenheit = 18.889° Celsius
