Summary
Convert Celsius, Fahrenheit, and Kelvin temperatures.
Calculation details
Temperature uses affine formulas rather than multiplicative factors and rejects values below absolute zero.
Formula
K = °C + 273.15; K = (°F − 32) × 5/9 + 273.15.
Worked example
Worked conversion
100 °C equals 212 °F.
How it works
Enter a temperature and choose scales. Conversion goes through Kelvin and rejects values below absolute zero.
Frequently asked questions
Does the calculation round the input?
No. The converter retains raw JavaScript numeric precision and delegates visible rounding to the existing display formatter.
Which unit definitions are used?
Conversions use Kelvin as the intermediate scale and reject temperatures below absolute zero.
