Convert celsius (°C) to fahrenheit (°F) with a transparent formula and reference values.
| Celsius | Fahrenheit |
|---|---|
| -40 °C | -40 °F |
| 0 °C | 32 °F |
| 10 °C | 50 °F |
| 20 °C | 68 °F |
| 25 °C | 77 °F |
| 30 °C | 86 °F |
| 37 °C | 98.6 °F |
| 100 °C | 212 °F |
1 °C = 33.8 °F. °F = (°C × 9/5) + 32 The interactive converter uses the same unit registry as this table, so the reference values and calculator stay synchronized.
Celsius: Celsius temperature scale.
Fahrenheit: Fahrenheit temperature scale.
Celsius and Fahrenheit have different zero points, so temperature conversion uses both multiplication and an offset. Multiply Celsius by 9/5, then add 32.
°F = (°C × 9/5) + 32
Celsius is used widely for weather, science and everyday temperature measurement, while Fahrenheit is common in the United States. Familiar reference points make it easier to interpret forecasts, cooking temperatures and room or body temperatures.
Short answers to common conversion questions.
Multiply Celsius by 9/5 and then add 32: °F = (°C × 9/5) + 32.
0 °C equals exactly 32 °F.
100 °C equals exactly 212 °F.
Celsius and Fahrenheit are equal at -40 degrees: -40 °C = -40 °F.
