How i can convert data from INCH to Millimeters

Hi,

In my coulmn data is presented in INCH form. and at the run time i have to convert that data from INCH to Millimeters. please can any one tell me how i can i do this.

If my memory serves me correctly, 1 inch = 2.54 cm = 25.4 mm

So just multiply your inch value by 25.4 and you should have your mm answer.
