Fahrenheit to Celsius Formula
To convert fahrenheit to celsius, subtract 32 from the temperature in fahrenheit, then multiply by 5/9. The formula is: °C = (°F − 32) × 5/9. This reverses the celsius-to-fahrenheit conversion by first removing the 32-degree offset, then scaling by the ratio of the degree sizes.
For example, to convert 98.6°F to celsius: (98.6 − 32) × 5/9 = 66.6 × 5/9 = 37°C. To convert 32°F to celsius: (32 − 32) × 5/9 = 0°C.

About Fahrenheit and Celsius
Fahrenheit is a temperature scale proposed by Daniel Gabriel Fahrenheit in 1724. It is primarily used in the United States, Belize, the Cayman Islands, and a few other territories. On this scale, water freezes at 32°F and boils at 212°F under standard conditions. Celsius, developed by Anders Celsius in 1742, is used worldwide in scientific contexts and by most countries for everyday temperature measurements. Converting fahrenheit to celsius is necessary for Americans traveling abroad, scientists collaborating internationally, home cooks using European recipes, and anyone reading global weather reports. Our fahrenheit to celsius converter provides exact conversions for any temperature value.
