    The problem is that you have set the 'precision' to have no decimal places, so it gets rounded off for display (but the actual number is ok until you save the values a second time).

    You can see that many of the values are displayed as '~ 6mm' the ~ means 'approximately', showing you that it cannot display all the decimal digits it needs to accurately display the value.

    In Sketchup, select
    Window
    Model Info
    Units
    and you should see a dialog as below.
    You need to change the 'Precision' entry to at least 1 decimal, or 2 as displayed below.
    You may even need 3 or 4 since imperial bit diameters can have many digits, like
    1/8" = 3.175mm
    1/16" = 1.5875mm
    and so on.
    Note that even in MM mode you can type 1/8" into an edit box and the correct value will be saved the first time you save it, the second time it will be rounded unless you have enough digits of precision available0
