Celsius vs Fahrenheit
Compare celsius and fahrenheit side by side, convert in both directions, and see the exact factor - Temperature units.
= 33.8 °F
= -17.2222 °C
0 °C = 32 °F (freezing point of water)
100 °C = 212 °F (boiling point)
Formula: °F = (°C × 9/5) + 32 · °C = (°F − 32) × 5/9
| Celsius (°C) | Fahrenheit (°F) | Fahrenheit (°F) | Celsius (°C) |
|---|---|---|---|
| 1 | 33.8 | 1 | -17.2222 |
| 2 | 35.6 | 2 | -16.6667 |
| 5 | 41 | 5 | -15 |
| 10 | 50 | 10 | -12.2222 |
| 25 | 77 | 25 | -3.8889 |
| 50 | 122 | 50 | 10 |
| 100 | 212 | 100 | 37.7778 |
| 250 | 482 | 250 | 121.1 |
| 500 | 932 | 500 | 260 |
| 1000 | 1,832 | 1000 | 537.8 |
Quick Answer
Celsius and Fahrenheit are two scales for the same quantity. Water freezes at 32 °F (0 °C) and boils at 212 °F (100 °C). The conversion is linear: °F = °C × 9/5 + 32, so a 1 °C step is a 1.8 °F step. 0 °F equals -17.7778 °C.
Key Facts
- 0 °C = 32 °F (water freezing point)
- 100 °C = 212 °F (water boiling point)
- °F = (°C × 9/5) + 32
- °C = (°F − 32) × 5/9
- A 1 °C interval equals a 1.8 °F interval
- US, Liberia, Myanmar use Fahrenheit daily; the rest of the world uses Celsius
Frequently Asked Questions
Which is bigger, a celsiu or a fahrenheit?
Temperature scales measure the same quantity with different zero points and step sizes, so "bigger" does not apply to the unit itself. A 1 °C interval is 1.8 times a 1 °F interval; 0 °C is 32 °F.
How do I convert celsius to fahrenheit?
Use the formula °F = (°C × 9/5) + 32. Example: 25 °C → 25 × 1.8 + 32 = 77 °F. Reverse: °C = (°F − 32) × 5/9.
Why are celsius and fahrenheit different?
They come from different measurement systems - Celsius belongs to the metric world, Fahrenheit to the US world (or another convention). The conversion is exact: 33.8 °F per celsiu, no rounding needed for the factor itself.
Is there a quick way to convert without a calculator?
Rough mental math: double the °C value and add 30. Exact: °F = °C × 9/5 + 32.
