Fahrenheit
Fahrenheit (°F) is a temperature scale primarily used in the United States, where water freezes at 32°F and boils at 212°F under standard atmospheric conditions.
History/Origin
Developed by Daniel Gabriel Fahrenheit in 1724, the Fahrenheit scale was one of the first standardized temperature scales and was widely adopted in the United States and some Caribbean nations. It was based on fixed points such as the freezing point of a saltwater solution and human body temperature.
Current Use
Today, the Fahrenheit scale is mainly used in the United States for everyday temperature measurements, including weather forecasts, cooking, and other domestic applications. Most of the world uses the Celsius scale, but Fahrenheit remains prevalent in specific regions and contexts.
Celsius
Celsius (°C) is a unit of temperature measurement where 0°C is the freezing point of water and 100°C is the boiling point at standard atmospheric pressure.
History/Origin
The Celsius scale was developed by Anders Celsius in 1742, originally with 0°C as the boiling point of water and 100°C as the freezing point, later reversed to its current form.
Current Use
Celsius is widely used worldwide for everyday temperature measurements, scientific research, and weather reporting, especially in most countries outside the United States.
