Convert Fahrenheit to Celsius instantly. Free online °F to °C converter with accurate results and formula explanation.
Formula
°C = (°F - 32) × 5/9Fahrenheit (°F) and Celsius (°C) are two common temperature scales. Fahrenheit is primarily used in the United States, while Celsius is used in most countries worldwide. Converting between these scales is essential for understanding weather forecasts, cooking recipes, and scientific data across different regions.
°C = (°F - 32) × 5/9The conversion subtracts 32 from the Fahrenheit value to account for the offset in freezing points, then multiplies by 5/9 to adjust the scale increment. Water freezes at 32°F / 0°C and boils at 212°F / 100°C.
