Minor League Equivalency calculator

Enter a player's minor league stats, select his current league and team,
and this will spit out equivalent stats at the major league level
You can also select a team and league for the equivalent stats. So in
addition to traditional MLEs (how would a minor leaguer fare in the majors?),
you can see how a player would do in a different league/level, or in a
different park in the same league.

Notes:

• MLE's are calculated using the league factors and formulas that
  Sean Smith shared with me. Thanks Sean!
• Minor league park factors are Dan Symborski's, and MLB's are those
  published at baseball-reference.com. NW Arkansas and Lehigh Valley
  are assumed to be neutral. I don't park-adjust walks or strikouts.
• FAQ: Why does the number of at-bats change?
  I hold plate appearances constant, so if walks or HBPs change,
  ABs change as well.
• Pitching calculator coming soon.
