Celsius (°C) to Kelvin (K) Converter
Unlike length or weight, temperature scales don't share a common zero point, so converting between them requires an offset in addition to a scale factor. This page covers the temperatures people convert most — cooking temperatures, weather readings, and common reference points like freezing and boiling.
Formula
K = °C + 273.15
