About Fahrenheit to Celsius Conversion
Fahrenheit (°F) is a temperature scale invented by Daniel Gabriel Fahrenheit in 1724. It is the primary temperature scale in the United States and some Caribbean nations. Celsius (°C), also known as centigrade, was developed by Anders Celsius in 1742 and is used by most countries worldwide, as well as in all scientific contexts.
The two scales meet at -40°, the only temperature that reads the same in both systems. Key reference points: water freezes at 32°F (0°C) and boils at 212°F (100°C). Converting Fahrenheit to Celsius is commonly needed when traveling abroad, reading international weather forecasts, following recipes from other countries, or interpreting medical thermometer readings. The formula is: °C = (°F - 32) × 5/9.
