Frequently Asked Questions
What is the formula?
°C = (°F − 32) × 5/9. Subtract 32 first, then multiply by 0.5556. For a rough estimate, subtract 30 and halve.
What is 100 °F in Celsius?
37.8 °C — just above normal body temperature, which is why 100 °F is a common fever threshold in Fahrenheit-using countries.
What is 350 °F in Celsius?
176.7 °C, usually written as 180 °C in recipes, which is gas mark 4. The oven chart lists the standard equivalents.
Why does the US still use Fahrenheit?
Largely inertia. Fahrenheit’s 0–100 range maps roughly onto human-experienced weather, which some find intuitive, and the cost of changing every thermostat, oven and forecast has kept it in place.
