Celsius to Fahrenheit (°C to °F)
0 °C = 32 °F
Formula: °F = °C × 9/5 + 32
How to convert Celsius to Fahrenheit
°F = °C × 9/5 + 32
To convert, multiply by 9/5 (1.8), then add 32. Example: 180 °C → 356 °F.
The two scales meet at −40°. Water freezes at 0 °C = 32 °F and boils at 100 °C = 212 °F (at sea level), so 100 Celsius degrees span 180 Fahrenheit degrees — a ratio of 9/5.
Needed for weather forecasts, oven temperatures in recipes, and body temperature when switching between metric countries and the US.
Mental shortcut: double it and add 30 (is within 2 °F for everyday temperatures between 0 °C and 20 °C; less accurate when hotter or colder).

Frequently asked questions
What is the formula to convert Celsius to Fahrenheit?
°F = °C × 9/5 + 32. In words: multiply by 9/5 (1.8), then add 32. For example, 180 °C → 356 °F. The two scales meet at −40°. Water freezes at 0 °C = 32 °F and boils at 100 °C = 212 °F (at sea level), so 100 Celsius degrees span 180 Fahrenheit degrees — a ratio of 9/5.
How do I convert degrees Celsius to degrees Fahrenheit?
Use °F = °C × 9/5 + 32: multiply by 9/5 (1.8), then add 32. Example: 180 °C → 356 °F.
Is there a quick way to estimate °C to °F in your head?
Yes — double it and add 30. This is within 2 °F for everyday temperatures between 0 °C and 20 °C; less accurate when hotter or colder. Use the exact formula (°F = °C × 9/5 + 32) when precision matters.
How do I convert degrees Fahrenheit back to degrees Celsius?
Use °C = (°F − 32) × 5/9 — subtract 32, then multiply by 5/9. See the Fahrenheit to Celsius page for a full chart.
