${\displaystyle T_{\mathrm {K} }=T_{\mathrm {C} }+273{,}15\ }$ 

• ${\displaystyle T_{\mathrm {K} }}$  : taẓɣelt akked kelven (K)
• ${\displaystyle T_{\mathrm {C} }}$  : taẓɣelt akked Selsius (°C)

${\displaystyle T_{\mathrm {K} }=(T_{\mathrm {F} }+459,67)/1,8}$ 

• ${\displaystyle T_{\mathrm {K} }}$  : taẓɣelt akked kelven (K)
