The formula is:(9/number of innings pitched) X (number of earned runs allowed)
For example, a pitcher who gave up 87 earned runs in 226 innings would have it figured like this:
9 / 226 X 87 = 3.46

multiply the total earned runs charged against his pitching by 9, and divide the result by the total number of innings he pitched.Anyone seen that Sportscenter Ad?
Earned runs given up, Multiplied by 9, divided by innings pitched. For example....If you pitch 9 innings and only give up 2 runs....2 runs X 9= 18 divided by 9 innings= era of 2.00Barry Bonds makes me sick. Agree or disagree?
There are actually different ways to write the equation, but the one I use is(ER/IP)*9=ERA
Where ER is earned runs credited to the pitcher and IP is his innings pitched. Remember that every 1 out is 1/3 of an inning pitched, so if a pitcher pitches 6 full innings and gives up 2 earned runs, his ERA is 3.00 [ (2/6)*9=3.00 ], but if he were to get 1 out in the 7th inning before being pulled without being attributed another earned run, his ERA would actually be 2.84 [ (2/6.33333)*9=2.84 ]. ERA is always to the hundreth decimal point and always rounded.
