- Enter the temperature.
- Choose the from unit.
- Read off your fahrenheit (°f), together with celsius (°c) and kelvin (k) — the calculator updates automatically, with no button to press.
Worked example
For example, with temperature of 100 and from unit of Celsius (°C), the fahrenheit (°f) is 212.00.
| Temperature | 100 |
|---|---|
| From unit | Celsius (°C) |
| Fahrenheit (°F) | 212.00 |
|---|---|
| Celsius (°C) | 100.00 |
| Kelvin (K) | 373.15 |

Frequently asked questions
Multiply the Celsius value by 9⁄5 and add 32. For example, 100°C × 9⁄5 + 32 = 212°F, the boiling point of water.
Subtract 32, then multiply by 5⁄9. For example, (212°F − 32) × 5⁄9 = 100°C. Just pick Fahrenheit as the from-unit and the calculator does it for you.
Kelvin is the scientific temperature scale that starts at absolute zero. To convert from Celsius, add 273.15, so 0°C is 273.15 K.
Water freezes at 0°C (32°F) and boils at 100°C (212°F) at sea level.
