Morphology

megaton = ton (transparent) = mega + ton

The word is transparently built from the prefix 'mega-' meaning one million and the base word 'ton'.

Etymology

The word megaton is made of mega-, which means 'million' and appears in words like megabyte, and ton, a common word for a large 'weight'. So a megaton literally means 'a million tons' of TNT, which is why we use it to describe very large explosive power.
