Leiden Scale to Kelvin

Leiden Scale (L): The Leiden Scale is a historical temperature scale used in the early 20th century, particularly at the Leiden University lab, for measuring extremely low temperatures, primarily for values below -183 °C.

Kelvin (K): The Kelvin scale is the base unit of thermodynamic temperature in the International System of Units (SI). It is an absolute temperature scale, meaning 0 K (absolute zero) is the point where all thermal motion ceases. It has no degrees symbol (°).
