Conversion Formula
Celsius → Fahrenheit: °F = (°C × 9/5) + 32 Fahrenheit → Celsius: °C = (°F − 32) × 5/9 Celsius → Kelvin: K = °C + 273.15 Kelvin → Celsius: °C = K − 273.15
About Fahrenheit to Celsius Conversions
Need to convert Fahrenheit to Celsius? This free tool handles the formula automatically. Enter your °F value and get the °C equivalent right away.
This conversion uses a non-linear (reciprocal) relationship, so a simple multiplication factor does not apply. The formula section below explains the method, and the reference table shows common converted values.
This page includes a reference table of common Fahrenheit values pre-converted to Celsius, the conversion formula, and frequently asked questions. All values use internationally recognized conversion standards.
Frequently Asked Questions
