Approximate Ratings of chess.com Computer Levels?

Im rated around 1000. I have a 200e notebook. Level 5 seems like below 900 compared with people on this website. It makes so much stupid mistakes there is no fun to play against it. Level six seems like at least 1100 or 1200 players I played against. Almost never any stupid mistakes and I can only beat it by thinking very long or taking back moves 2-3 times per game.

i can't even pass level 1 wtf 

you know the basics of the openings but after that you have no clue what to do. You can register on chesstempo.com and do at least a hundred tactic puzzles in chesstempo.com/chess-tactics.html then try again against the computer  

lol, black butler... that game was not 1800, lol

lmfao that's a 1200 elo game...

5 moves in you were blundering already

According to the app, level 10 is 2600. Level 9 is 2000 and below that it drops 200 points each level.

Hmm, I just beat level nine. I didn't just beat 2000 elo. All I did was a gambit/trick to take the center early on in the London system, then attacked f7 until overloaded and it sacrificed its queen to avoid mate by force, then I was 8 up in material, mopped up the pawns, created some forks and promoted a pawn. I think a 2000 elo would have spotted the danger in my pawn move without any doubt, the computer just didn't even care though. Weird. So now I'm playing level ten next (beat every other level). Its probably my computer capacity letting it blunder like that, I just don't see why it drops so many pawns and allows mate threats. Ah well... Guess you can't use it to tell your elo. I am new to playing here started at 1200 lost the first few games acclimating all which cost hundreds of lost points, then now I keep winning seven in a row over and over and win back like 6 points at a time. It got tedious slowly grinding back up to better players so thought itd be a shortcut to play the comp to see where I should be. But no way I played 2000 elo, those dudes thrash me.
btw, the goofy ending was cuz I wasn't bothered about calculating for draws by mating neatly with pawn and queen, thats why its super ugly. But really e5 at the start was a move I set up with bf4, and I have no idea why it didn't notice I was targetting f7 to weaken the fianchetto, it just gave me that pawn... I couldn't believe it. So obviously I then targetted it, move 32 rd7 was the crucial move, threatening mate or taking his queen by force. Just so simple of a game, it gave me the center and a huge lead in development. Also weakened f7 for me like a gift... he also could have played Qb8 then Qe8 to avoid losing his queen, but just either didn't see it or chose to give me it? Like who doesn't move the queen there?

What device are you using to play these games? The strength of the program depends on the strength of your hardware.

Here's a game I played against Computer Level 9. It is not weak on my hardware.

I've only done one game vs level 3 and I think a fast processor on your computer does a lot for it's rating.

I have an old (last tournament 12/1/2000) 1395 USCF regular rating - am just getting back to serious study, have no problem beating Chess King's 1700-rated robot as white or black, am challenged by Lucas Chess's 1400-1600 rated "Lucas-Elo" engine characters, won a live 10-min. blitz game here vs a 1245-rated opponent,  but I just tried level 3 here at Chess.com for the first time on a fast quad-core, 3.2 GHz processor laptop and lost with the White pieces where the computer played the Nimzowitsch Defense (1 e4 Nc6) and I tried to turn it into a Bishop's Opening or Vienna Game with 2 Bc4 which evolved into an irregular position that chessgames.com says occurred 5 times from 1992-2016 that 2 win for each side and 1 draw.  I managed to go up a piece for a pawn at the expense of a fairly exposed O-O-O castle'd king and cramped position. The level-3 computer made ok to excellent moves for about 15 consecutive moves to block my K-side attack on his castle while penetrating my Q-side.  I have chess.com analyze the game, then had Houdini 2 do the same through Chess King 2016 Standard.

I've coached a lot of 800-1000 level high-school beginning tournament players and they would not have seen far enough ahead to make the moves chess.com's level 3 did - though I have a pretty fast processor on my laptop.

I've come to learn that I left too many holes in my tactical understanding before studying positional stuff - I coached a high school team to 3 -consecutive county championships and 3rd, 4th, 5th in state in those years, so I had to get a little ahead of myself to advise players who were better than myself. I'm working on getting thinking and my tactics down now before moving on.

I'm rated 1800+ on here (right now I'm, 1842 I think) and I have had a REALLY hard time trying to

beat level 7, I haven't been able to do it yet in about 10 attempts. I beat level 6 but not on the first attempt.

Computer 1-easy is like 500

Thanks I just tried it on my ipad and it was much easier. Funny I never thought I was playing against my local machine. 

Yeah its terrible on my machine, I have to put it on level ten to get any decent moves from it. So regarding the OP, don't judge your elo off this, just select the level you want.

I wonder if there is a way we can get more accurate ratings than just guessing.  How would it work?  I imagine somebody with a powerful computer but under strict time control (so no ponder) have the different levels of chess.com computer play a bunch of against engines with known ELO (roughly speaking of course, perhaps engines that has played hundreds of games against other engines and high level players).   

From what I remember, it is an old version of Stockfish (6?) compiled in Javascript and running single-threaded through the user's browser's JS engine. Utilising the UCI option for strength.

I've tested it against some other engines. It is slightly weaker than Stockfish 8 on 25 ply (only slightly). On the Elo scale as used in TCEC compared to Stockfish 8 I'd say the Level 10 engine is somewhere around 2900-3000. I've checked its moves and almost all of them match perfectly with Stockfish 8 (it occasionally makes a "microblunder" but that's because it doesn't search very far). Level 9 is also tough but I would put it much lower on the scale because I have decent chances of beating it (so I would rate it ~2100-2200 TCEC Elo).
