There are a few ways to do it. One easy formula:
Earned runs X 9 / innings pitched
An example - Pitcher A pitches 56 innings and gives up 23 runs:
23 X 9 / 56 = 3.70

Number of runs allowed per 9 innings. So if a pitcher allows 2 earned runs in 6 innings than his ERA for that game would be 3.00 .

(ER/IP) * 9 = ERA
Where ER is the number of earned runs attributed to the pitcher and IP is the number of innings pitched.
Also, remember that every out scored is 1/3 of an inning for the pitcher. So if a pitcher goes 7 full innings and then gets 1 out before being pulled, that's 7.3333333 IP for him. Or, if he is a reliever and gets one out before being pulled, that's 0.333333 IP for him.
ERA is a measure of how many earned runs a pitcher will give up on average if he pitches one regulation game (9 innings). The first part of the formula determines how many ER he is averaging giving up for 1 IP, and you multiply that average over 9 innings with the second step.

ERA- Earned Run Average,
The number of earned runs (not including runs made possible because of errors) allowed by a pitcher divided by nine (Innings).
