Noob question : How much is 1 sol in hashes

How much is 1 sol in hashes. Sorry I am new to ZCash mining. I have MSI RX 580 8 gbs each producing around 23 MH/s. How do I convert it in hashes, as I wanted to calculate the ROI.

1sols = 1 hash

What miner you're using ?

I see you coming there :sunny:
