Amu's are used instead of grams to express things like atomic and molecular weights. 1 amu is equal to 1/12 the mass of a single carbon-12 atom. This is equal to 1.66 x 10^-24 g. Carbon-12 has a mass of exactly 12 amu.

The atomic or molecular mass of an atom is such a small number that it would be impractical to use grams or pounds for computations.

1 u equates to 1.660538782(83)×10−24 g.

Because the weight in grams would be infinitesimally small.

Why is kelvin used as measurement for temperature instead of degrees celsius?

Kelvin is an absolute scale, which makes much more sense once you understand that temperature is related to the speed of atoms (they can't have a negative speed). An absolute scale is one in which the lowest possible temperature is zero. An absolute scale also makes more sense in thermodynamics, where the ratios between two temperatures are often important.
