Is 65 milliometers bigger or 5 centimeters bigger?

65 millimeters 
5 centimeters=50 milimeters

Yes i see that 65millimeter is bigger than 5centimeter because, let me prove that 65millimeter is bigger than 5centimeter,now start,65/1000 is equal to 0.065 the 1000 is milli mean 1000.and centimeter mean 100 so 5/100 is equal to 0.05 so 65 is millimeter bigger than 5 centimeter.

The answer would be 397.9 hope this helps:)
