This page opens the temperature converter preset to Fahrenheit → Celsius. The exact formula is °C = (°F − 32) × 5/9: subtract 32 first, then multiply by 5/9 (about 0.5556). The subtraction handles the offset between the scales' zero points; the ratio handles the different degree sizes.
Key reference points: 32 °F = 0 °C, 50 °F = 10 °C, 68 °F = 20 °C, 98.6 °F = 37 °C, and 212 °F = 100 °C. In the kitchen, a 350 °F oven — the most common American baking temperature — is 176.7 °C, and 425 °F for roasting is about 218 °C.
