Detailed explanation-1: -A degree on the Fahrenheit scale is a BIGGER unit than a degree on the Celsius scale (Think-freezing and boiling points of water on both scales). Energy is transferred as heat from a substance at HIGH temperature to a substance at LOW temperature. Energy is transferred as heat between two objects of SAME temperature.
Detailed explanation-2: -The Conversion 100 degrees separate freezing and boiling on the Celsius scale, but for Fahrenheit the difference is 180 degrees. This means Celsius is 1.8 times larger than Fahrenheit. To put another way, 1 degree Fahrenheit is 5/9 degree Celsius.
Detailed explanation-3: -Therefore, a temperature difference of one degree Celsius is greater than a temperature difference of one degree Fahrenheit. Since 100 Celsius degrees span the same range as 180 Fahrenheit degrees, one degree on the Celsius scale is 1.8 times larger than one degree on the Fahrenheit scale (because 180100=95=1.8).
Detailed explanation-4: -To convert between Fahrenheit and Celsius, you need to visualize the “size of a step” represented by 1 degree. Since there are 180 Fahrenheit steps between freezing and boiling and only 100 Celsius steps between freezing and boiling, Fahrenheit steps are about half as big. (They are exactly 5/9ths as big).
Detailed explanation-5: -Fahrenheit scale is proposed by taking 32 °F as a freezing point of water and 212 °F as a boiling point of water. Whereas in the Celsius scale 0 °C is the freezing point of water and 100 °C is the boiling point of water.
