Question 1

How accurate is this Fahrenheit to Celsius converter?

Accepted Answer

We use the usual exact definitions (for example 1 inch = 25.4 mm). For everyday work the result is more precise than you will need.

Question 2

Does my data leave the browser?

Accepted Answer

No. This tool computes locally. Closing the tab discards the input unless you copy or download the result.
