About Leiden (ºL)

The Leiden scale, denoted by ºL, is a historical temperature scale named after the Dutch city of Leiden. It was developed by Willem Jacob's Gravesande, a Dutch physicist, in the 18th century. In this scale, the freezing point of water is defined as 0 degrees Leiden (0 ºL), and the boiling point of water is defined as 150 degrees Leiden (150 ºL).

About Kelvin (K)

Kelvin is the base unit of temperature in the International System of Units (SI). It is defined such that absolute zero, the absence of all thermal energy, is 0 Kelvin (0 K). One Kelvin is equal in size to one degree Celsius, but the Kelvin scale starts at absolute zero.
