Difference between molecular mass and molar mass

The molecular mass is the mass of 1 molecule in amu(atomic mass unit) example: mass of 1 H2O molecule is 18 amu
Molar mass is the mass of 1 mole of molecules i.e. mass of 6.022 *10^23 molecules.It is the same number as Molecular mass but the unit is grams. ( Mass of 6.022 *10^23 molecules of H2O is 18 grams.)
