Here's why:
* The scales are different: The Celsius scale is based on the freezing and boiling points of water at standard atmospheric pressure. 0°C is the freezing point, and 100°C is the boiling point. The Fahrenheit scale uses different reference points (32°F for freezing, 212°F for boiling).
* The size of a degree: A 1°C difference is equivalent to a 1.8°F difference. This means that a 1°C change in temperature is smaller than a 1°F change in temperature.
In summary:
* 1 degree Celsius is smaller than 1 degree Fahrenheit.
* 1 degree Celsius is equivalent to 1.8 degrees Fahrenheit.
