Convert $ 59^\circ $ $ F $ to Celsius scale:
 $ \left( A \right)332^\circ $
 $ \left( B \right)15^\circ $
 $ \left( C \right) - 214^\circ $
 $ \left( D \right)10^\circ $

Hint: To convert temperatures in degrees Fahrenheit to Celsius, subtract $ 32 $ and multiply by $ .5556 $ (or $ \dfrac{5}{9} $ ).
We can write it as,
 $ ^\circ C = (^\circ F - 32) \times \dfrac{5}{9} $ .

Complete step-by-step answer:
 Fahrenheit and Celsius are the scales mostly used for reporting room, weather, and water temperatures. The Fahrenheit scale is used in the United States, while the Celsius scale is used worldwide.
Given question is convert the temperature into Celsius,
Substitute the given degree in the equation that becomes,
 $
   \Rightarrow ^\circ C = (59 - 35) \times \dfrac{5}{9} \\
   \Rightarrow 27 \times \dfrac{5}{9} \\
   \Rightarrow 3 \times 5 \\
   \Rightarrow 15^\circ C \;
  $
Therefore, $ 59^\circ $ $ F $ into Celsius is $ 15^\circ C $ .
So, the correct answer is “ $ 15^\circ C $ ”.

Note Fahrenheit and Celsius are the scales mostly used for reporting room, weather, and water temperatures. The Fahrenheit scale is used in the United States, while the Celsius scale is used worldwide.
Shortcut method for doing this is,
 $ \Rightarrow $ Subtract $ 30 $ from the Fahrenheit temperature and then divide by two.
 $ \Rightarrow $ The 18th-century German physicist Daniel Gabriel Fahrenheit originally took as the zero of his scale the temperature of an equal ice-salt mixture and selected the values of $ 30^\circ $ and $ 90^\circ $ for the freezing point of water and normal body temperature, respectively.
