About this tool
This page opens the temperature converter preset to Fahrenheit → Celsius. The exact formula is °C = (°F − 32) × 5/9: subtract 32 first, then multiply by 5/9 (about 0.5556). The subtraction handles the offset between the scales' zero points; the ratio handles the different degree sizes.
Key reference points: 32 °F = 0 °C, 50 °F = 10 °C, 68 °F = 20 °C, 98.6 °F = 37 °C, and 212 °F = 100 °C. In the kitchen, a 350 °F oven — the most common American baking temperature — is 176.7 °C, and 425 °F for roasting is about 218 °C.
Reach for this when reading American recipes, weather reports, pool or aquarium guides and device specs. Enter Fahrenheit to get Celsius live, or type Celsius in the other field to convert backwards; the formula in use is always displayed under the result.
Example. 0 degrees Celsius converts to 32 degrees Fahrenheit and 273.15 kelvin.
Limit. The scales are Celsius, Fahrenheit, and kelvin, with no Rankine scale.
