When you need this conversion

Weather is the everyday use, but cooking is where precision matters most — oven temperatures like 180 °C versus 350 °F appear in recipes written on opposite sides of the Atlantic. Body temperature is the other high-stakes case: 37 °C is normal, and 38 °C (100.4 °F) is the standard fever threshold used by most health authorities.
