Kelvin is of Scottish origin and means 'from the meadow'. It is also a unit of temperature measurement, named after Lord Kelvin, a physicist who formulated absolute zero temperature on the scale. This name gained popularity in the 20th century but has since become less common. It is associated with energy, heat, and scientific pursuits due to its connection to the Kelvin scale.
"Kelvin experienced fluctuations in popularity over the years, with its highest peak in 1972 at 13 births and lowest in several years at just 5 births."
