- Fahrenheit to Celsius is the Fahrenheit number minus 32, times 5, divided by 9.
- 0°C is 32°F. 100°C is 212°F. Those are the freezing and boiling points of water at standard pressure.
- −40 is the only temperature that is the same number on both scales.
- A result that is not a short decimal is shown to 2 decimal places. A comma in a number is a thousands separator.
This is arithmetic. It is not a forecast, and it does not say what temperature a room or a person should be.
