Can you post your original gravity and refractometer reading for final gravity?

I'm still on the lookout for a reliable conversion.
In my experience, there is NO completely accurate conversion. What does work is that when the refractometer reading is the same over several days, you know it's done fermenting, and often it's "close enough" even if not totally accurate.

I still usually check FG with a hydrometer and skip the refractometer after fermentation begins.

+1 to this. I use the refractometer exclusively during brewday and that's it. I might use a hydrometer to check FG, but in all honesty I rarely check FG. Not best practices I know, but if you're confident in your fermentation, who cares?

I depend on my hydrometer for the final gravity, but my go to for the OG is the refractometer. It would be nice to get the reliable conversion for a refractometer FG, but I understand the dozens of variables involved.
