Well, on the Celsius scale....we set #0# #""^@C# #-=# #"the normal freezing point of water"#

And on the #"temperatura assoluta"# scale, #"the normal freezing point of water"-=273.15*K#...

Here, the #"absolute or Kelvin temperature scale"# sets ZERO at #-273.15# #""^@C#...the point at which all molecular motion ceases...

#"Temp"("K") = "Temp"(""^@"C") + 273.15#

#"Temp"(""^@"C") = "Temp"("K") - 273.15#

#0^@"C"= "273.15 K"#

#"0 K" = -273.15^@"C"#

A change in temperature of #1# Kelvin is equivalent to a change of #1^@"C"#, so they have the same magnitude.

However, the Kelvin scale is based on #"0 K" \ =# #"absolute zero"# (the coldest possible temperature where atoms have no thermal movement).

The Celsius scale is based on #0^@"C" = "freezing point of pure water"# (at standard sea-level pressure).

The two scales are related by a difference of #273.15#.

#T("K") = T(""^@"C") + 273.15#

#T(""^@"C") = T("K") - 273.15#
