Converting Celsius to Fahrenheit is essential when traveling to the United States, following American recipes, checking international weather forecasts or understanding medical temperature readings in Anglo-Saxon countries.

The Fahrenheit scale shifts the zero and uses a different graduation from Celsius. The conversion formula accounts for these two differences: a 32° offset and a 9/5 multiplication factor.

📐 Formula

°F = (°C × 9/5) + 32 or °F = (°C × 1.8) + 32

📊 Reference table

Celsius (°C) Fahrenheit (°F) Reference
-40 -40 Equality point
-20 -4 Very cold
0 32 Freezing point
10 50 Cold
20 68 Room temperature
25 77 Warm
37 98.6 Body temperature
100 212 Boiling water

💡 Practical examples

Example 1: 20°C (office temperature) (20 × 1.8) + 32 = 36 + 32 = 68°F. A room at 20°C is 68 degrees Fahrenheit.
Example 2: 37°C (fever) (37 × 1.8) + 32 = 66.6 + 32 = 98.6°F. Normal body temperature is 98.6°F in Fahrenheit.
Example 3: 180°C (cooking oven) (180 × 1.8) + 32 = 324 + 32 = 356°F. An oven set to 180°C corresponds to about 356°F (often rounded to 350°F).
