About the Temperature Converter
Convert temperatures between Celsius, Fahrenheit and Kelvin. It is helpful for cooking, weather, science and travel.
How to use the Temperature Converter
- Enter the Value and select the Scale you are starting from.
- Press Calculate to see the temperature in the other scales.
Formula and method
°F = °C × 9/5 + 32 · °C = (°F − 32) × 5/9 · K = °C + 273.15
Worked example
25 °C = 25 × 1.8 + 32 = 77 °F. Water boils at 100 °C = 212 °F = 373.15 K. The two scales meet at −40, where −40 °C equals −40 °F.
Anchor points. Water freezes at 0 °C (32 °F) and boils at 100 °C (212 °F). Normal body temperature, 37 °C, is 98.6 °F. −40 is the same in both scales.
When to use the Temperature Converter
- Reading weather forecasts and oven temperatures from other countries.
- Converting lab and science values between Celsius, Fahrenheit and Kelvin.
- Setting a thermostat or a cooking temperature correctly.
Common mistakes to avoid
- Just doubling Celsius and adding 30. It is only a rough shortcut and gets worse at extremes.
- Forgetting that Kelvin has no degree symbol and no negative values.
Tips
- A quick estimate from Celsius to Fahrenheit is to double the number and add 30.
- Kelvin has no degree sign and 0 K is absolute zero.
