I would like to know if it's possible to get a rough idea of what my ELO is and how accurate those methods are.

For example, I did one of those "chess tests" and the results it gave me didn't quite seem right. I did the one on ELOMeter.net, and got the following:

Based on your move choices, our estimate of your Elo rating is 1464, with a 95% confidence interval of [1302...1627].

That doesn't sound right. Based on how things have been going for me on chess.com, it seems very high. Believe me, I'd LIKE to be higher on the ELO scale. But the result I got from ELOMeter.net didn't seem right.

If I were to look at the United States Chess Federation rankings, I'd probably rate myself roughly either a G (600–799) or an F (800-999).

    Why would you believe any test of your puzzle ability could possibly be as good a measure as your online rating (on Chess.com, Lichess, etc.)? Although they are not the same system and not on the same scale (and also not at classical controls) (and online rather than OTB), these differences pale in comparison to the difference between puzzle ability and in-game playstrength.

    If you're playing large numbers of games and your rating is fluctuating wildly, then your playstrength is fluctuating wildly. Elo would show this in the same way that Chess.com rating does. I'm not sure what the real question is here? Do you just want confirmation that Elometer.net is pretty much useless as anything but a curiosity/trivia measure?

    'I'm just curious' isn't a clear question. Please state precisely what you want to know. If you are curious what your Glicko rating might be, just look at your Chess.com rating. That doesn't satisfy you because it vacillates a lot? Then you don't have one rating. Your rating vacillates a lot. Are you asking the correlation between Chess.com and FIDE Elo ratings? If so, that's totally unclear from the question. The two answers you've had address completely different guesses as to what you actually want to know.

    Can you share your profile with chess.com? We'll see your rating for your previous months and then let you know if it's fluctuating.

    In addition to the link posted by @Hauptideal, you could also check out ethanlebowitz.github.io/RatingConverter/index.html, assuming you play on Lichess. I'm over 2200 FIDE and it's accurate within 30 points for me.

Puzzles are a notoriously bad estimator for ELO. (Tried myself, wild fluctuations.) You could run whole games by you through an engine (moar input => moar output) and check the accuracy of your moves. There is a whole scientific paper dedicated to how valid this method is.

  • Interesting paper. I disagree a bit though. I think from just one person's perspective, we can have a direct correlation between quality of moves and their approximate Elo.

If you have online chess ratings, you can get a very rough estimate here, but you should expect that a significant deviation to your real rating is possible (+-200).

Puzzles are not very good for getting a close approximation of your ELO, for a variety of reasons. The are some websites that allow you to play games with a computer rated at a certain ELO, playing a few of these games (with the clock, and in proper match conditions) can help get a reasonable estimate of your ELO. Obviously the more games you play the better an estimate you can get. For instance if you can consistently beat a computer rated at 1300 ELO but consistently lose to a computer rated 1500 ELO, you’d know your somewhere around the 1400 mark.

Already posted this link as a comment, but since this question isn't closed anymore I'll leave it in an answer too:

ethanlebowitz.github.io/RatingConverter/index.html

Does a decent job of approximating what someone's FIDE rating would be, given their Lichess ratings. You mentioned chess.com though, so not sure if you also play on Lichess.
