It depends on the material.

If the same asteroid that created the 225m wide crater on moon hit earth instead it would burn up in earth atmosphere if it was rocky in nature (~3.6m wide, 73 tons).

If the crater was made by a mostly iron asteroid, it would create a 12.5m crater on earth (~2.3m wide, 51 tons).

The reason for this is that rocky asteroids shatter thus have bigger surface area to burn up.

Iron asteroids stay solid and survive the atmosphere much easily.
