2,5 cm = 1 inch  10mm  = 1 cm    (25mm = 1 inch)

9/16 x 2.5 = cm  convert to mm  this is too large
1 and 1/2 inch = 3/2 x 2.5cm  convert to mm  too small
the correct size would be between the one that is too small and the one that is too large.

I think you wrote something wrong you have 9/16 is more than one and a half please check.
