USCF Ratings vs chess.com standard ratings?

Hey all! I'm hoping to participate in my first USCF rated tournament this coming Saturday. I mostly just play standard games here on chess.com (time control 15m + 10s). My chess.com standard rating lately has been hanging between 1500 and 1550. I'm trying to estimate what my USCF rating would be so I sign up for a section appropriate to my level. To those of you who have USCF ratings and play enough standard chess here on this site, what are your USCF ratings and what are your chess.com standard ratings? 

Oops! I'm seeing this sort of question has been asked a lot before. Feel free to ignore this post, unless you feel particularly kind hearted and are willing to give me extra info!

I would suggest playing in one of the lower sections, unless you just want to have an extra challenge, then play in the Open section if that is an option.
