Key Differences
Kevin, a male first name, is derived from the Irish name Caoimhín, rooted in the Gaelic elements 'caomh' meaning noble or gentle and 'gein' meaning birth. On the other hand, Kelvin is the base unit of temperature in the International System of Units (SI), representing the thermodynamic temperature scale, and it is named after the British physicist and engineer Lord Kelvin (William Thomson).
Kevin is widely used across English-speaking countries and has various cultural references, including famous personalities and fictional characters. Kelvin, while also used as a first name, is more commonly recognized in scientific contexts, specifically in physics and engineering, for its application in thermodynamic temperature measurements, such as absolute zero or boiling points.
The popularity of Kevin peaked in the mid-20th century, making it a relatively modern name compared to many traditional names with ancient origins. Kelvin as a unit of measurement was established in the late 19th century, reflecting the period's scientific advancements and the contribution of Lord Kelvin to thermodynamics.
Kevin's use in popular culture, such as movies, music, and sports, contributes to its familiarity and popularity as a first name. Kelvin, aside from its scientific significance, is less frequently encountered in daily language, unless discussing scientific topics, temperature scales, or when used as a somewhat less common first name.
While Kevin has no direct relation to scientific principles or measurements, the name Kelvin is intrinsically linked to the physical sciences, illustrating the diverse origins and uses of these terms. Kevin's association with characteristics such as handsomeness and nobility contrasts with Kelvin's association with precise scientific measurement and principles.

Kevin
Kevin () is the anglicized form of the Irish masculine given name Caoimhín (Modern Irish: [ˈkiːvʲiːnʲ]; Middle Irish: Caoimhghín [ˈkəiṽʲʝiːnʲ]; Old Irish: Cóemgein [ˈkoiṽʲɣʲinʲ]; Latinized as Coemgenus).

Kelvin
The kelvin is the base unit of temperature in the International System of Units (SI), having the unit symbol K. It is named after the Belfast-born Glasgow University engineer and physicist William Thomson, 1st Baron Kelvin (1824–1907). The kelvin is now defined by fixing the numerical value of the Boltzmann constant k to 1.380649×10−23 J⋅K−1.
