RC/27 is runs created per 27 outs, basically extended out to show what a lineup of 1 player would create over (27 outs) = 9 innings.
Giambi created 122 runs last year, of the 877 NY scored. His RC/27 was 7.92.
That means a lineup of 9 Giambis would score 7.92 runs over 162 games. Considering the run average was 4.72 per 27, you can see Giambi was 3.20 runs per 27 over average.
Lineup of 9 Giambis scores 7.92
Lineup of 9 average player's scores 4.72
