Aliasing Data value in DataGridView

I am using single table to fetch values in datagridview. Lets say i have two columns, ComponentName, Speed. In Torque column, i have limit on values like from 1 to 7. So, while fetching i can get values in this range. However, for each speed with value, say 1, is 100rpm which is not present in any database field. So, in the datagridview i want to display 100rpm instead of 1. How can i do it. Ideas appreciated.

Thanks.
