How it works

Celsius and Fahrenheit use different zero points and degree sizes. This converter first moves all inputs to Celsius, then transitions to the desired output unit. Kelvin adds a 273.15 offset to the Celsius scale and is common in scientific settings.

Because the relationships are linear, the conversion is lossless. Rounding is applied only when displaying results to keep the values readable.
