America is one of only 3 countries still using Fahrenheit for daily temperature. When Americans travel to Europe, Canada, or check international weather apps, they need instant °F to °C conversion. Our free tool converts Fahrenheit to Celsius in one click, no math needed.
This converter is perfect for travelers checking London or Paris weather, chefs converting oven temperatures for international recipes, students working on science projects, and doctors reading medical reports. Room temperature 72°F becomes 22.2°C. Normal body temperature 98.6°F becomes 37°C.
Enter any Fahrenheit value in the box above and click Convert. The result shows instantly in Celsius. Works on mobile and desktop. No signup required. Use decimal values too – 72.5°F converts accurately to 22.5°C. Bookmark this page for quick access anytime.
The exact formula is: °C = (°F - 32) × 5/9
Example: 72°F: (72 - 32) × 5/9 = 40 × 5/9 = 22.2°C. For quick mental math, subtract 30 from °F and divide by 2. For 72°F: (72-30)/2 = 21°C, which is close to the exact 22.2°C.
| Fahrenheit °F | Celsius °C | Use Case |

Travel: When Americans travel abroad, weather apps show Celsius. Convert instantly to know if you need a jacket.
Cooking: International recipes use Celsius for oven temps. 350°F oven = 177°C.
Science: Labs and schools worldwide use Celsius for experiments and data.
Health: Medical charts use Celsius. Fever is 100.4°F = 38°C.
Is 0°F equal to 0°C? No. 0°F = -17.8°C. 0°C = 32°F. They are different scales.
Why does USA use Fahrenheit? Historical reasons from British system. Daniel Fahrenheit created it in 1724 with 32°F as freezing point.
Can I convert negative temperatures? Yes. -40°F = -40°C. That’s where both scales meet at one point.
