Frequently asked questions
How do you convert Fahrenheit to Celsius?
Use the formula °C = (°F − 32) × 5/9. Type a value into the box above and the converted temperature appears instantly.
What is a common reference point?
Water freezes at 0°C / 32°F / 273.15 K and boils at 100°C / 212°F / 373.15 K at sea level — handy anchors to sanity-check any conversion.
Why isn't it a simple multiplication?
Because the scales don't share a zero. Fahrenheit's zero and Celsius's zero are different temperatures, so you shift as well as scale.
