FAQ
What are the conversion formulas?
°F = °C × 9/5 + 32, and K = °C + 273.15. The tool converts your input to Celsius first, then to the other scales.
Can I enter negative temperatures?
Yes. Note that Kelvin can't go below 0 (absolute zero); the tool still shows the math but such values aren't physically meaningful.
How precise are the results?
Results are rounded to two decimal places, which is plenty for everyday and most scientific use.
