Fahrenheit to Celsius Converter
Convert temperature measurements between Fahrenheit (°F) and Celsius (°C) instantly with precise conversion formulas.
°C = (°F − 32) × 5/9 | °F = (°C × 9/5) + 32
What is the Fahrenheit to Celsius Converter?
The Fahrenheit to Celsius Converter is a free digital tool built to translate temperature readings from the Fahrenheit scale (°F) to the metric Celsius scale (°C). While Fahrenheit is primarily used in the United States and a few other regions, Celsius is the standard temperature metric used globally.
Whether you are tracking foreign weather reports, adjusting oven baking temperatures, or analyzing scientific data, this bidirectional converter delivers instant and precise results.
How Does the °F to °C Conversion Work?
The tool calculates equivalent temperatures utilizing standard algebraic formulas:
Fahrenheit to Celsius
Subtract 32, then multiply by 5/9: °C = (°F - 32) / 1.8.
Celsius to Fahrenheit
Multiply by 9/5, then add 32: °F = (°C × 1.8) + 32.
Real-Time Processing
Computes values down to multiple decimal points instantly as you type.

Frequently Asked Questions (FAQ)
How do I convert Fahrenheit to Celsius manually?
To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit value and then divide by 1.8 (or multiply by 5/9). For example, (77 °F – 32) / 1.8 = 25 °C.
What is 72 degrees Fahrenheit in Celsius?
72 degrees Fahrenheit is equal to approximately 22.22 degrees Celsius ((72 – 32) × 5/9).
What temperature is both Fahrenheit and Celsius the same?
The temperature scale intersects at -40 degrees, meaning -40 °F is exactly equal to -40 °C.
