Celsius and Fahrenheit are the two most commonly used temperature scales in the world. While Celsius is used by the vast majority of countries and all scientific research, Fahrenheit remains the standard in the United States for weather, cooking, and everyday use.
The Celsius scale was developed by Anders Celsius in 1742 and is based on the properties of water: 0°C for the freezing point and 100°C for the boiling point at standard atmospheric pressure. This makes it intuitive for scientific applications.
The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit in 1724. It uses 32°F for the freezing point and 212°F for the boiling point of water. The smaller degree increments can provide more precision for everyday temperatures without decimals.
Converting between the two is straightforward: multiply Celsius by 9/5 and add 32 to get Fahrenheit, or subtract 32 from Fahrenheit and multiply by 5/9 to get Celsius. A useful reference point: -40° is the same in both scales.
