About This Category

The sports calculators turn counting stats into rates that can be compared across players, teams and eras. A hitter with 150 hits in 500 at-bats is not obviously better than one with 120 in 380 — until both are expressed as .300 and .316.

Definitions differ between leagues, so the pages follow the standard convention for each sport: earned runs are scaled to nine innings, field goals count two- and three-pointers alike, and pass completion treats crosses separately.

Frequently Asked Questions

Why do baseball rates appear as .300 without a leading zero?

It is traditional notation: .300 means 300 per thousand, not 0.3 runs. The convention exists so that a rate and a counting total cannot be confused on a scoreboard.

How many attempts before a percentage becomes meaningful?

Roughly 300 plate appearances in baseball, 300 field-goal attempts in basketball and 150 free throws. Below that, random variation is larger than the real difference between an average and a good player.

Can I compare players from different leagues?

Only with care. Park dimensions, scoring environments and rules all differ, which is why adjusted metrics such as OPS+ exist. The raw rate says what happened; the adjusted figure says how good it was in context.
