Frequently Asked Questions
What is the formula?
°F = (°C × 9/5) + 32. Multiply by 1.8 and add 32. For a rough estimate, double and add 30 — accurate to a couple of degrees over normal weather ranges.
What is 180 °C in Fahrenheit?
356 °F, usually rounded to 350 °F in recipes, which is gas mark 4. The oven chart lists the standard settings.
What is normal body temperature?
37 °C is 98.6 °F, though the true average is slightly lower at around 36.6 °C. A fever is generally considered 38 °C (100.4 °F) or above.
At what temperature are the scales equal?
−40. It is the only point where °C and °F give the same number.
