Temperature Conversion Chart (Fahrenheit to Celsius)
Switching between Fahrenheit and Celsius is easy once you have the formula — and even easier with a chart. Here's how to convert both ways, plus the temperatures people look up most.
The formulas
- Fahrenheit to Celsius: subtract 32, then multiply by 5/9. C = (F − 32) × 5/9
- Celsius to Fahrenheit: multiply by 9/5, then add 32. F = (C × 9/5) + 32
