Roughly how much greater is the energy released by hydrogen fusing into helium compared to forming water chemically?

Answer

Ten million times greater

The energy released when four hydrogen nuclei turn into one helium nucleus is immense, calculated to be roughly ten million times greater than the energy produced by the chemical reaction of hydrogen combining with oxygen to form water.
