btw I have lived in Canada all my life and I to am "metrically challenged" lol
Did you use a micrometer to get these measurements?
Would it be fair to say
the thickness is 1/6 of an inch?
the width is 7/8 of an inch?
the length is 1 and 2/5 of an inch?
Sorry I am trying to convert these to fractions of an inch or as close as I can.
Thanks again for the replies.
