Stockfish Material counting

[fishchess]

I see material value big , for example Knight value is 781 but i know Knight value is 325

  PawnValueMg   = 126  
  KnightValueMg = 781 
  BishopValueMg = 825   
  RookValueMg   = 1276
  QueenValueMg  = 2538

How to convert this value to real value?

Are they divided into numbers somewhere?

These are stockfishs internal values.
It adjusts the score when it reports back the info
score * 100 / 208 (old but still relative for HCE)

note: there’s no fixed value a piece should have

[vondele]

In the classical evaluation, the convention was to divide by PawnValueEg, which was 208, to convert to pawns.
