Celsius vs. Fahrenheit: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Celsius, a metric temperature scale, sets the freezing point of water at 0°C and boiling at 100°C, while Fahrenheit, used primarily in the U.S., sets these points at 32°F and 212°F, respectively.
Key Differences
Celsius is part of the metric system, widely used worldwide, where 0°C marks the freezing point of water and 100°C its boiling point. Fahrenheit, predominantly used in the United States, sets water's freezing point at 32°F and boiling point at 212°F.
