To convert Fahrenheit to Celsius: °C = (°F − 32) × 5/9. This tool handles any temperature including decimals and sub-zero values.
Key Reference Points
32°F = 0°C — water freezes
68°F = 20°C — comfortable room temperature
98.6°F = 37°C — human body temperature
212°F = 100°C — water boils
-40°F = -40°C — the two scales meet
When You Need This
Most useful when reading US weather forecasts, American cooking recipes (oven temperatures), or US medical references. Fahrenheit can seem counterintuitive if you grew up with Celsius.
Common Use Cases
Converting weather reports to Celsius when travelling
Adjusting oven temperatures between Fahrenheit and Celsius
Understanding fever temperature thresholds across both scales
Travel planning — understanding temperatures in unfamiliar units
