PostPosted: Tue Sep 22, 2015 11:50    Post subject:  SteamID conversion tables  
Conversion can be done between Legacy Format (old steamid), Modern Format (new steamid) and Community ID (SteamID64).

Considering that one SteamID is known:

Legacy Format : STEAM_0:x:y (ex. STEAM_0:0:6364948)
Modern Format : [U:1:z] (ex. [U:1:12729896])
Community ID : c (ex. 76561197972995624)

Legacy Format => Modern Format
Code:
formula. (y * 2) + x = z

ex. (6364948 * 2) + 0 = 12729896


Legacy Format => Community ID
Code:
formula. ((y * 2) - x) + 76561197960265728 = c

ex. ((6364948 * 2) - 0) + 76561197960265728 = 76561197972995624


Community ID => Legacy Format
Code:
If c is odd then x = 1
If c is even then x = 0

formula. ((c + x) - 76561197960265728) / 2 = y

ex. ((76561197972995624 + 0) - 76561197960265728) / 2 = 6364948


Community ID => Modern Format
Code:
formula. c - 76561197960265728 = z

ex. 76561197972995624 - 76561197960265728 = 12729896


Modern Format => Community ID
Code:
formula. 76561197960265728 + z = c

ex. 76561197960265728 + 12729896 = 76561197972995624


Modern Format => Legacy Format
Code:
If z is odd then x = 1
If z is even then x = 0

formula. (z - x) / 2 = y

ex. (12729896 - 0) / 2 = 6364948
