How to Convert Celsius to Fahrenheit
The formula to convert Celsius to Fahrenheit is: °F = (°C × 9/5) + 32. Or equivalently: °F = (°C × 1.8) + 32. For a quick mental estimate, double the Celsius temperature and add 30 — this is accurate to within a few degrees for typical weather temperatures.
Key reference points: 0°C = 32°F (water freezes), 20°C = 68°F (comfortable room temperature), 37°C = 98.6°F (normal body temperature), 100°C = 212°F (water boils at sea level). Common weather conversions: 10°C = 50°F, 15°C = 59°F, 20°C = 68°F, 25°C = 77°F, 30°C = 86°F, 35°C = 95°F, 40°C = 104°F.
Oven Temperatures
Converting oven temperatures between Celsius and Fahrenheit is one of the most common cooking conversions. 180°C = 356°F (moderate oven), 200°C = 392°F (hot oven), 220°C = 428°F (very hot oven). Most ovens in the US show Fahrenheit while European ovens show Celsius, making this conversion essential for international recipes.
