Question about how to convert H/s to Sol/s

[zefirka]

Hello, I'm wonder at this code.

Is this ZEC-specific? Or may be equihash-specific. I have found a lot of contradictory information about how to convert hashes to solutions. Most of people say that 1 H/s is firmly 1 Sol/s, but in this code I found that 1 Sol/s = 0.5 MH/s. I'm completely confused with that.

Can someone explain what is going on about sols and hashes?

equihash-specific
Colloquially the terms are used interchangeably.
On a technical level equihash solves problems, rather than attempting to match random hashes to a known hash, so the term is "solution" to a problem that it solves (because, math) vs "hashes" that are attempted.
That's an over-simplified explanation, but it's the "best" short answer.
