Halbeega Thermometerka ee lagu qiyaaso Heerkulka. Gees ka mid ah waa Salsiyas, dhanka kalena waa Kelfin.

Kelfin (Af Ingiriis : Kelvin; Af carabi: كلفن) waa halbeeg lagu xisaabiyo heerkulka. Ereyga Kelfin waxaa loogu magac daray Injineer reer England Baron Kelvin (1824–1904) kaas oo sameeyay Halbeeg cabir dhamaystiran[1].

Halbeegan waxaa loo soo gaabiyaa K (Kelfin).

Qiyaasta halbeegan jabjab ahaan waa 1/273.16[2]). Cabirkan oo inta badan lagu qiyaaso kuleylka iyo qaboowga ayaa wuxuu lambar todoba ka yahay Halbeegyada Caalamiga ah ee dunida.

Marka halbeega Kelfin loo bedelaayo Salsiyas waa +273.16.

Tusaale ahaan haddii heerkulka maanta yahay 30 °C markaad Kelfin u bedelayso waa +273.16 taas oo u dhiganta 303.16 K.

Kilven waxa uu ka midyahay halbeega cabir ee heerkulka waxaana loo suntaa (K), waxa uu lamid yahay cabirada kale ee lagu cabiro kuleelka.

Derajada Kilven = sentigaret + 273,15, oo udhiganta K = °C + 273,15

Darajada Kilven = (Fahrenhayt + 459.67)/1.8 K = (°F + 459,67) / 1,8
