Convert Celsius to Fahrenheit

Celsius to Fahrenheit is the most requested temperature conversion because recipes, weather reports, and HVAC systems often mix these two scales. Celsius is used almost everywhere in the world, while Fahrenheit remains common in the United States. The relationship between the two scales combines a multiplication factor and an offset: each Celsius degree is 1.8 Fahrenheit degrees, and the Fahrenheit scale begins 32 degrees above the Celsius freezing point.

The formula is straightforward: °F = (°C × 9/5) + 32. That means 0°C becomes 32°F, 100°C becomes 212°F, and room temperature (about 22°C) becomes roughly 71.6°F. Remembering a few anchors makes this conversion intuitive: −40°C equals −40°F, 20°C equals 68°F, 37°C (body temperature) equals 98.6°F, and 180 Fahrenheit degrees span the same interval as 100 Celsius degrees between freezing and boiling.

Use this converter when following a recipe that lists oven temperatures in Celsius, checking international weather forecasts, configuring HVAC equipment, or verifying lab and manufacturing temperatures for equipment specified in Fahrenheit. The calculator applies the exact formula instantly, so you can avoid rounding mistakes and keep precision for sensitive tasks like baking, thermodynamics calculations, or quality control.

For mental math, multiply by two, subtract 10%, then add 32. For example, 25°C × 2 = 50; 10% of 50 is 5; 50 − 5 = 45; 45 + 32 = 77°F (exact result is 77°F). This quick trick is close enough for daily estimates while the converter gives you precise results.
