The quick rule for your head
Double it, take off 10%, add 32: for 25 °C → 50 − 5 + 32 = 77 °F, exactly right (the shortcut IS the formula, rearranged). For weather at a glance, memorise the ladder of nice numbers: 0/32, 10/50, 20/68, 30/86, 37/98.6 — each 10 °C step is 18 °F.
Where this conversion shows up
Weather is the daily driver — a US forecast of 95 °F means nothing until it becomes 35 °C — followed by cooking, where American recipes bake at 350 °F (about 175 °C) and European ovens dial Celsius. Body temperature completes the set: the American 98.6 °F fever threshold is simply 37 °C restated.

Questions people ask
What is the Celsius to Fahrenheit formula?
°F = °C × 9/5 + 32. The 9/5 scales the degree size (Fahrenheit degrees are smaller), and the +32 shifts the zero, because 0 °C — freezing water — sits at 32 °F.
What is 37 °C in Fahrenheit?
98.6 °F — normal body temperature, and the reason that oddly precise number is printed on American thermometers. Fever territory starts around 38 °C / 100.4 °F.
What temperature is the same in both scales?
−40. Minus forty Celsius equals minus forty Fahrenheit exactly — the crossing point of the two lines, and a genuinely useful sanity check for any converter.
What is 180 °C for baking in Fahrenheit?
356 °F — recipes round it to 350. The common oven ladder: 160 °C ≈ 325 °F, 180 ≈ 350, 200 ≈ 400, 220 ≈ 425.
