Frequently Asked Questions
What is the formula to convert Celsius to Fahrenheit?
°F = (°C × 9/5) + 32. For example, 25 °C = (25 × 1.8) + 32 = 77 °F.
Why is -40 the same in both scales?
Because at -40, (°C × 9/5) + 32 = °C — the conversion formula maps -40 back to -40. It is the one temperature where both scales read identically.
Where is Fahrenheit still used?
The United States, its territories, and a few Caribbean nations (Bahamas, Cayman Islands) still use Fahrenheit for everyday weather.
