Fahrenheit to Celsius converter

Convert U.S. temperature readings into metric values so you can compare weather, oven settings, and travel conditions more easily.

How this conversion works

To convert Fahrenheit to Celsius, subtract 32, multiply by 5, and divide by 9. This formula is widely used for weather reports, baking guidance, and international travel comparisons.

Formula: °C = (°F - 32) × 5 / 9.

Assumptions: This tool uses the standard formula for converting temperature scales and is designed for general everyday use rather than precise measurement in regulated scientific environments.

Worked example: 77°F converts to 25°C, which is a common comfort-temperature reference and useful for resting or room-temperature estimates.
