Convert Degrees Celsius to Degrees Fahrenheit (°C to °F)
°F = °C × 1.8 + 32. Convert degrees Celsius to degrees Fahrenheit with the exact formula, a common-values table and a free converter.
Conversion formula
°F = °C × 1.8 + 32
Temperature scales set their zero in different places, so this is an offset conversion, not a ratio. There is no single number you can multiply by: °C 0 is 32 °F, and doubling the input does not double the result. Apply the multiplier, then the offset, in that order.
°C to °F table
| Degrees Celsius (°C) | Degrees Fahrenheit (°F) |
|---|---|
| 0 °C | 32 °F |
| 1 °C | 33.8 °F |
| 2 °C | 35.6 °F |
| 5 °C | 41 °F |
| 10 °C | 50 °F |
| 20 °C | 68 °F |
| 50 °C | 122 °F |
| 100 °C | 212 °F |
Every figure is computed at build time by the site’s own converter from the temperature unit registry. For a value that is not listed, put it into the interactive converter.
Frequently asked questions
What is 1 °C in °F?
1 °C is 33.8 °F. Because temperature scales are offset rather than proportional, this figure is not a multiplier: 100 °C is 212 °F, not 100 times 33.8.
What is the formula to convert degrees Celsius to degrees Fahrenheit?
°F = °C × 1.8 + 32. Apply the multiplier first, then the offset. Every value in the table on this page is computed with that formula by the same converter the tool below runs.
How do I convert degrees Fahrenheit back to degrees Celsius?
Use the inverse formula, °C = °F × 0.555555556 - 17.7777778. The °F to °C page carries the same table in that direction.
