Why Convert Temperature from Fahrenheit to Celsius?
The Celsius scale (°C) is the most widely used temperature scale globally, used by the vast majority of countries for weather forecasts, cooking, and scientific measurements. Converting Fahrenheit to Celsius is essential when communicating internationally or following recipes and guidelines from most countries outside the US.
Whether you're traveling abroad, working with international colleagues, or using metric-based scientific equipment, understanding Fahrenheit to Celsius conversion is invaluable.
What is Fahrenheit?
The Fahrenheit scale (°F) is a temperature scale used primarily in the United States and some Caribbean nations. It was proposed by physicist Daniel Gabriel Fahrenheit in 1724.
- Water freezes at 32°F
- Water boils at 212°F (at standard atmospheric pressure)
- Normal human body temperature is approximately 98.6°F
- The scale has 180 degrees between freezing and boiling points of water
What is Celsius?
The Celsius scale (°C), also known as centigrade, is the standard temperature scale used in most of the world. It is part of the International System of Units (SI).
- Water freezes at 0°C
- Water boils at 100°C (at standard atmospheric pressure)
- Normal human body temperature is approximately 37°C
- Named after Swedish astronomer Anders Celsius
