To convert length x width x height dimensions from inches to millimeters we should multiply each amount by the conversion factor. One inch equals 25.4 millimeters, in order to convert 25 x 1 x 77.4 inches to millimeters we have to multiply each amount of inches by 25.4 to obtain the length, width and height in millimeters. In this case to convert 25 x 1 x 77.4 inches into millimeters we should multiply the length which is 25 by 25.4, the width which is 1 by 25.4, and the height which is 77.4 by 25.4. The result is the following:
25 x 1 x 77.4 inches = 635 x 25.4 x 1965.96 millimeters

To calculate a inch value to the corresponding value in millimeters, just multiply the quantity in inches by 25.4 (the conversion factor).
millimeters = inches * 25.4
The factor 25.4 is the result from the division 1 / 0.0393701 (millimeter definition). Therefore, another way would be:
millimeters = inches / 0.0393701
