Meaning and origin of Kelvin
Kelvin is a Scottish name that is usually said to mean “from a Scottish river name”.
Kelvin comes from the River Kelvin, which flows through Glasgow in Scotland. The meaning of the river's name is uncertain, though it is probably of Celtic origin. The physicist William Thomson took the title Lord Kelvin from the river, and the kelvin, the base unit of temperature in the international system of units, is named after him. As a given name, Kelvin has been used since the twentieth century, especially in Scotland, the United States and parts of Africa and Asia. It sounds bright and clever, and Kel is a simple nickname.
