Does temperature mean heat? i'm confused!

Definitely, temeprature is not heat, though these concepts
are mixed up frequently.

Heat is the kinetic energy of
molecules within a substance, while the temperature is a
number.

Temperature is measured in different units
(Kelvin,Celsius), while heat is measured in units of energy
(Joules).

There is a relation between heat and temperature:
the average kinetic energy of molecules within a substance is directly proportional to
the temperature measured in Kelvin units.
