What is mega in power of 10?

Excuse me, but could you clarify what you mean by 'mega' in the context of power of 10? Is it referring to a specific prefix used in scientific notation to represent a factor of 1,000,000 or one million, as in megabytes for digital storage? Or are you asking about some other usage of 'mega' in relation to powers of 10 that I'm not familiar with? Could you provide more context or elaborate on your question?
