Created a utility (windows exe) that would do as specified in the subject.

Example:

:: Glicko2 to Elo Rating Estimator ::

"Converts blitz Glicko2 to standard Elo rating"

[1]
Glicko2 Rating: 2000
Rating Deviation: 90

Elo: 1789

Lower Elo: 1662
Upper Elo: 1917
Confidence Level: 95%

[2]
Glicko2 Rating: 2800
Rating Deviation: 80

Elo: 2355

Lower Elo: 2242
Upper Elo: 2468

If you think it does not estimate well, post your Lichess blitz rating and your FIDE standard Elo rating so I can update this program.

My FIDE rating is below 1000, because my national rating is 700.
Lichess rating is extremely inflated, try decreasing 1200 points to your rating to have an idea.

For what it's worth, in a pool of the same players under the same conditions, etc. Glicko-2 and Elo ratings should be approximately the same...

So the estimator is actually converting from lichess to FIDE, not from Glicko-2 to Elo.

Blitz Glicko2: 1955
RD : 65.25
Standard Elo: ?

Is your national rating equivalent to standard elo rating?

Your data can be:

Glicko2 Rating: 1955
Rating Deviation: 62.25

Elo: 1758

Lower Elo: 1670
Upper Elo: 1846
Confidence Level: 95%

I looked at some of your blitz rating here in Lichess and I can see that you should be above 1000 elo.

My blitz Glicko2 is around 2100, RD 80.

That can be.

Glicko2 Rating: 2100
Rating Deviation: 80

Elo: 1860

Lower Elo: 1747
Upper Elo: 1973
Confidence Level: 95%

My standard FIDE Elo is around 1900, so it is within the Lower and Upper Elo which is fine.

If you have a data, [Lichess Blitz rating and Standard FIDE elo], post it here. I will update the program with those data.

I threw in some numbers and for me personally it seems fairly accurate (whatever that means).

You have to remember different people think differently.
Some people will greatly improve if you give them time.
Im not one of them though lol.

Interesting, they can link chess.com-uscf-fide.

If people here are interested, we can do a similar survey. I will create a survey form.

For example a survey can be.

Lichess Classical
Lichess Blitz
Lichess Bullet
Lichess Training
Chess.com Blitz
FICS Blitz
FIDE Standard
Other sites (Blitz)

Once we get some data, we can then create a gui to query some rating conversions.

Post if you are interested.
