ERA stands for Earned Run Average. The number of innings per game determines how ERA is calcuated. In Major League Baseball they play 9 innings so ERA is calculated with this equation, Earned Runs divided by 9. High School Baseball (at least where I am located) plays 7 innings as a regulation length game. In this case a pitcher's ERA is Earned Runs divided by 7. In Little League the a regulation game is 6 innings, so ERA would be determined by Earned Runs divided by 6. If you are playing a game and it goes in to extra innings then a pitcher's ERA is not affected by the extra innings. If a regulation game is 6 innings, and the game goes into the seventh inning, then a pitcher's ERA is still determined by # of earned runs divided by 6. In summary ERA is ALWAYS determined by the amount of Earned Runs allowed divided by the number of innings played (not including extra innings).
No. The ERA is calculated the same in all levels and is based on 9 innings.

Well, I can't swear they're the worst of the worst but the 1930 Philadelphia Phillies hold the MLB record for highest team ERA in a season at 6.71. That season, Les Sweetland pitched 167 innings to an ERA of 7.71 (record was 7-15) and Claude Willoughby pitched 153 innings to an ERA of 7.59 (record was 4-17). Jim Walkup of the 1937 St. Louis Browns pitched 150 1/3 innings to an ERA of 7.36 and record of 9-12. His career 6.74 ERA over 462 1/3 innings is the highest in MLB's modern era for pitchers that threw at least 400 innings in a career. More recently, Jose Lima had a 6.99 ERA in 168 2/3 innings (record was 5-16) for the 2005 Kansas City Royals and a 6.65 ERA in 196 1/3 innings (record was 7-16) for the 2000 Houston Astros.
1) Multiply the total number of earned runs by the number of innings in a full game (most fastpitch leagues play 7 inning games but some youth leagues play 6 inning games). 2) Divide the total number of innings pitched into the number derived from 1) above and round to the second decimal place. Using 17 innings pitched and 4 earned runs ... For games that are 7 innings in length, the ERA would be 1.65 (4 times 7 equal 28 and 28 divided by 17 equal 1.647 which is rounded to 1.65). For games that are 6 innings in length, the ERA would be 1.41 (4 times 6 equal 24 and 24 divided by 17 equal 1.411 which is rounded to 1.41).
ERA is based on 9 innings pitched. When you see a pitcher with a 4.94 ERA that means for every 9 innings pitched, he gives up 4.94 earned runs. Example: A pitcher has pitched 150 innings and given up 60 earned runs. 1) Divide the number of earned runs (60) by the number of innings pitched (150) =0.40. 2) Then take that number (0.4) and multiply it by 9 =3.60. A pitcher who has pitched 150 innings and given up 60 earned runs has an ERA of 3.60.
There are 6 outs per inning and there are 7 innings in one complete game. Do the math 6x7= 42
You adjust the formula for regulation game length. So it becomes ER*7/IP (Remember to convert fractional innings to their approriate decimal values).
To figure ERA take the total number of earned runs and multiply by 7 (which is a complete game in softball) then divide by innings pitched.
softball has 7 innings in less a tie then they play more innings if one team is winning by a lot they have the mercy rule and they call the game
In Texas, High School baseball games are 7 innings long, and I believe that is the same around the country. If the game is tied at the end of the 7th inning, it continues until there is a winner.
usually about 7 innings
7 innings:)
