Baseball Earned Run Average

The earned run average is the average number of allowed earned runs normalized to the length of a full game.

The earned run average equals the number of earned runs divided by the sum of the innings pitched and the outs divided by 2 multiplied by 9.

Formula

QuantityVariable["ERA", "Unitless"] == (9*QuantityVariable["ER", "Unitless"])/(QuantityVariable["IP", "Unitless"] + QuantityVariable["OUTS", "Unitless"]/3)

symbol description physical quantity
