What Fahrenheit to Celsius | °F to °C can do:

Each input line is converted using the formula °C = (°F − 32) × 5/9. You can toggle rounding for simpler output or show the full equation for every line.

The tool flashes the output box when changes are made so you can spot them quickly. It also shows a live item counter just below the output. Line spacing is preserved if you turn on the “Keep empty lines” toggle useful for keeping file formats consistent.

Example:

Input:

32
212
-40
98.6

Output (with formula on):

32°F − 32 × 5/9 = 0.00°C
212°F − 32 × 5/9 = 100.00°C
-40°F − 32 × 5/9 = -40.00°C
98.6°F − 32 × 5/9 = 37.00°C
