Formula

—

The converter changes the input temperature to Celsius first, then converts from Celsius to the target scale.

25°C equals 77°F. 0°C equals 32°F and 273.15 K.

This tool supports Celsius, Fahrenheit, and Kelvin.

Kelvin cannot be below absolute zero. The converter warns when a result would be invalid.

Conversions use standard formulas and rounded display values, which are enough for everyday temperature checks.
