Multiply the Fahrenheit value by the conversion factor: °C = (°F − 32) × 5/9. This calculator applies the exact factor automatically and rounds the display to ten significant figures.
How do I convert Celsius back to Fahrenheit?
Divide by the same factor — conversion factors work in both directions, so the reverse calculation is just the inverse of the forward one.
How accurate is this Fahrenheit to Celsius conversion?
The math runs on exact SI definitions and international standard factors, with results rounded only for display (ten significant figures). That is far tighter than any practical measurement tolerance.
