How to calculate FIDE rating?

If someone has 2000 Lichess rating then what FIDE rating they estimate

lol, How did you get those estimations @TheKingClash?

Little precision for the first estimation

2000 Lichess Rapid = 1695 FIDE rapid
2000 Lichess Blitz = 1855 FIDE blitz

if it means anything...

@TheKingClash said in #4:

For players 1800 - 2000 Lichess:

Lichess rapid X 0.89 - 65 = FIDE
Lichess blitz X 0.96 - 65 = FIDE

If the second-to-last digit of the player's rating is 8 or more, and the hundreds digit is odd, round up to the nearest hundred.
For players 1600 - 1800 Lichess, subtract 95 instead of 65
For players 1400 - 1600 Lichess, subtract 125 instead of 65
For players 1200 - 1400 Lichess, subtract 125 instead of 65
For players 1000 - 1200 Lichess, subtract 95 instead of 65
For players 800 - 1000 Lichess, subtract 65 instead of 65
For players 600 - 800 Lichess, subtract 55 instead of 65
For players 2000 - 2200 Lichess, subtract 55 instead of 65
For players 2200 - 2400 Lichess, subtract 50 instead of 65
For players 2400 - 3000 Lichess, subtract 45 instead of 65

Wow!

subtract 1000 simple

unless your fide rating is above 1300 it should work

What do you mean by subtract 1000 @TalMagicalDragon?
