Loona Calculators
Convert celsius to fahrenheit instantly — type any value and the result appears as you type. Below you will find the exact formula, a °C to °F conversion table and a worked example.
Formula: Fahrenheit = (°C × 9/5) + 32. Multiply the Celsius temperature by 9, divide by 5, then add 32.
Question: How many fahrenheit is 37 °C — normal human body temperature?
Steps: Take the value in celsius: 37 °C. Apply the formula: Fahrenheit = (°C × 9/5) + 32. That gives 37 → 98.6 °F (rounded to four decimal places).
Result: 37 °C = 98.6 °F.
| Celsius (°C) | Fahrenheit (°F) |
| -40 °C | -40 °F |
| -20 °C | -4 °F |
| -10 °C | 14 °F |
| 0 °C | 32 °F |
| 5 °C | 41 °F |
| 10 °C | 50 °F |
| 15 °C | 59 °F |
| 20 °C | 68 °F |
| 25 °C | 77 °F |
| 30 °C | 86 °F |
| 37 °C | 98.6 °F |
| 40 °C | 104 °F |
| 50 °C | 122 °F |
| 100 °C | 212 °F |
Need a value that is not in the table — or the reverse direction? Use the converter at the top of this page or the fahrenheit to celsius converter, or the full Unit Converter for every unit in one place.
Use the formula °F = (°C × 9/5) + 32. For example, 20 °C × 9/5 = 36, plus 32 = 68 °F. The converter above applies it instantly.
There is no fixed number — the scales start at different zeros. Each 1 °C step equals a 1.8 °F step, and the anchor points are 0 °C = 32 °F and 100 °C = 212 °F.
40 °C = 104 °F — a hot day, and a high fever if it is a body temperature.
Use the reverse conversion — our fahrenheit to celsius converter does it instantly.
At −40. −40 °C and −40 °F are the same temperature — the only point where the two scales meet.
