What's the formula for calculating ERA in baseball?
138629
You take the number of earned runs and divide by the number of innings pitched. Then multiply by 9.\n\nYou multiply by 9 because an ERA is the average number of earned runs a pitcher gives up per full game.

ok say the Yankees are 21-10\nand the red sox are    18-12\n\nyankees won 2 more so thats 2 games\nand red sox loss 3 more so that 3\n2 + 3 = 5 \n5/2=2.5\ntherefore the yankees are 2.5 games up\nits the average between games won and loss\nhope this helps

These are kind of fun if you apply dimensional analysis over and over again.  Lets assume that our years are 365, 365, 365, 366 days, and that we'll experience two leap years in the time span.  This is then 8*365 + 2*366 days, which is our starting point\n\n3652 days\n\nnow we know that there are 24 hours = 1 day, so take this formula and multiply both sides by (1/day) to get 24 hours/day = 1.  Since multiplying by 1, by this equation multiplying by 24 hours/day does not change value\n\n3652 days * 24 hours / day\n\nNow cancel the "day" term in the numerator and denomenator\n\n3652 * 24 hours\n\nNow do the same thing for minutes and then for seconds.  60minutes/hour = 1 so\n\n3652 * 24 * 60 hours * minutes / hour\n\ncancel hour and apply 60 seconds/minute = 1\n\n3652 * 24 * 60 * 60 minutes * seconds / minute\n\nand cancel the minute term and perform the multiplication:\n\n315,532,800 seconds

I included some of the pre-1900 leagues, in addition to the American and National Leagues.\n\n1) Cy Young: 290 NL + 221 AL = 511\n2) Nolan Ryan: 135 NL + 189 NL = 324\n3) Gaylord Perry: 139 AL + 175 NL = 314\n4) Bobby Mathews: 131 NA (National Association) + 106 AA (American Association) + 60 NL = 297\n5) Fergie Jenkins: 169 NL + 115 AL = 285\n6) Gus Weyhing: 115 AA + 119 NL + 30 PL (Players League) = 264\n7) Randy Johnson: 147 AL + 116 NL = 263\n8) Denny Martinez: 141 AL + 104 NL = 245\n9) Jim Bunning: 118 AL + 106 NL = 224\n10) Kevin Brown: 102 AL + 109 NL = 211\n11) Al Orth: 100 NL + 104 AL = 204

GAME TIMES\n\n\nAll games are limited to 1-1/2 hours (90 minutes). \nNo new inning may begin after 1 hour and 15 minutes (75 minutes) from the official start of the game. If the home team is trailing by 5 runs or less, any inning started must be completed. If the visiting team is trailing at 1 hour and 30 minutes, the last two innings will not be played. \nAll games are limited to five (5) innings (exception is tied games). \nA 6th inning is allowed in a tied game if time permits, as noted above. A 7th inning is NOT ALLOWED. \nThe visiting team Pitching Machine Umpire is the official time keeper. \nThe visiting team Pitching Machine Umpire will note official start time to scorekeeper who will record start time in scorebook. \nNote: Late starting games must end no later than 90 minutes from the scheduled start time. \nTHE VISITING TEAM\n\nIs listed first on the schedule \nUses the third base dugout \nTakes infield/outfield for practice twenty (20) minutes prior to game time \nProvides the Pitching Machine Umpire (Head Umpire) for their own FARM GAME to be played. This umpire is the official time keeper and will note the official start time to scorekeeper who will record start time in the scorebook. \nSets up the pitching machine and bases. \nTHE HOME TEAM\n\nIs listed second on the schedule \nUses the first base dugout \nTakes infield/outfield for practice ten (10) minutes prior to game time \nProvides the official scorekeeper \nProvides the volunteer base umpire for their own FARM GAME to be played. \nPuts away the pitching machine and bases. \nTHOSE PERMITTED ON FIELD\n\nOnly players on the official rosters of participating teams (no siblings, parents, friends, scorekeepers). \nOnly one manager and two coaches in the dugout and in the coaching boxes per team. \nUmpires wearing official DLL umpire attire. \nManagers and coaches must remain in the dugout or coaching box until time is called and permission is granted by the Pitching Machine Umpire to leave the dugout or coaching box. \nOnce time is granted, a manager or coach may visit the pitcher;s mound and confer with any player. \nTwo adult base coaches are permitted (managers are encouraged to use at least one player coach on the offense). Team player base coaches must wear protective helmets. Coaches physically assisting a base runner while time is in will result in the base runner being called out. \nNote: umpires have the authority to approve photographers to be on the field. \nUMPIRES\n\nIf team-provided umpires are not available (Home and Visiting teams) to umpire their own scheduled FARM game, the team Manager or Coach will umpire the game. \nThe Pitching Machine Umpire is stationed behind the pitching machine, protects players from the pitching machine and makes calls in the outfield, at 3rd base and home plate. \nAfter a player does not swing at five (5) consecutive pitches, the Pitching Machine Umpire shall call balls as strikes to encourage players to swing at the pitched balls. \nUmpires are not to coach while on the field umpiring. \nThe base umpire makes calls at 1st and 2nd base and keeps track of runnerÕs positions at the conclusion of each play. \nPLAYING TIME\n\nEqual playing time for ALL FARM players is a priority. National Little League Rules dictate that every player will participate in each game defensively for a minimum of six consecutive outs and bat at least one (1) time each game (rule Ivi). Exception: DLL modified rules require every player participate defensively for a minimum of half of total team innings played at which they were present during the entire season. For example, if a team plays five defensive innings, all players will have the opportunity to participate in two innings each, however some players will have opportunity to participate in one additional inning. The manager is responsible to adjust playing time in the next game(s) to rectify this inequity. \nAll players must start at least every other game at which they were present dur

it would take amazingly long time to type up how to play baseball. ill give a short explanation. there is 4 bases in a diamond shape, then an outfield. a pitcher throws the ball trying to get it past the batter and over the home plate (a base) for a strike. 3 strikes and your out. \nthere are 3 outs in one inning. you play nine innings. if you hit the ball, you run up the dirt ob the right to first base. if the ball is cought while the first baseman touches the bag, your out. if you see that you could maybe get to 2nd base, turn and run there. you score by going all the way around the bases and touching home plate. oh, and if you hit a ball over the fence in between the to polls in left and right field, its a home run

7 Innings, and the time depends on how long each inning is
