FanGraphs Guts! (wOBA & FIP Constants)

One of the frequently asked questions we get is what are the wOBA constants for a particular season, or what is the FIP constant?

Now there is a single exportable page with all the answers: FanGraphs Guts!

– Any field with a “w” in front of it is a wOBA constant

– R/PA is runs per plate appearance

– R/W is the runs to wins conversion number

– cFIP is the FIP constant

Awesome! The FIP constant has been something I’ve always wanted available.

Well I guess I can stop randomly plugging in other constants to try and reverse-engineer the formula.

Avogadro’s number got me a touch closer than Planck’s constant. Graham’s number was the least useful.

Or even reverse-engineer the constants.
