How to calculate
Convert Celsius into Fahrenheit and Kelvin.
°F = °C × 9/5 + 32; K = °C + 273.15
Worked example
Celsius (°C): 20.
Fahrenheit: 68 °F; Kelvin: 293.15 K.
Assumptions and limits
Temperatures below absolute zero are not accepted.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.
Understanding the result
Fahrenheit and Kelvin describe the same temperature entered in Celsius. Temperature conversions include an offset, not just a scaling factor.
When this tool is useful
Translate a temperature reading between common scales.
Understanding your inputs
| Input | What to enter |
|---|---|
| Celsius (°C) | Enter a number of at least -273.15 and no more than 1000000000. |
Frequently asked questions
Is 0°C the same as 0 K?
No. Zero Celsius equals 273.15 Kelvin. Absolute zero is −273.15°C.
Can I convert a temperature difference with this tool?
This converts an absolute temperature. For differences, a Celsius degree equals a Kelvin increment, and the Fahrenheit difference is 1.8 times as large without adding 32.
