Celsius to fahrenheit

Quick answer

To convert Celsius to Fahrenheit, multiply by 9, divide by 5, then add 32. So 180°C = 356°F and 200°C = 392°F. To reverse it, subtract 32, multiply by 5, then divide by 9.

The Celsius to Fahrenheit formula

The formula is simple: °F = (°C × 9/5) + 32. However, remembering it mid-recipe is a hassle, so this Celsius to Fahrenheit converter does the maths for you.

The quick way to convert (and the exact way)

The exact formula is °F = (°C × 9 ÷ 5) + 32, and to go back, °C = (°F − 32) × 5 ÷ 9. For a rough mental estimate you can double the Celsius figure and add 30 — but be careful, that only gets you in the ballpark (180°C estimates as 390°F when the real answer is 356°F). For oven temperatures, where 20 degrees changes your bake, use the exact table above rather than the shortcut.
