How do I convert Fahrenheit to Celsius manually?

Subtract 32 from the Fahrenheit temperature, then multiply by 5/9 or divide by 1.8 to get the Celsius equivalent.

Can I convert Celsius to Fahrenheit using this tool?

Yes, the converter includes a Swap function that reverses the conversion direction, allowing you to input a Celsius value and get the Fahrenheit equivalent.

What are the freezing and boiling points of water on these scales?

Water freezes at 32 degrees Fahrenheit and 0 degrees Celsius, and boils at 212 degrees Fahrenheit and 100 degrees Celsius at standard atmospheric pressure.

Is the conversion exact or an approximation?

The conversion formula is exact, but displayed results are rounded to a limited number of decimal places depending on the input value.
