When i did my new blue face over lay,it came from the good old USA and has miles per hour in big #'s and kilometers in real small #'s,so i drive by a rule my dad taugh me ---take whatever "kilometers posted" per hour and multiply by 6 and then drop the"0"at the end. Example----100KPHx6=600,drop the "0"=60MPH---this ballpark figures(actual is 62. 5MPH) i drive by,not exactly but close enough for me. Dad had a old 72Dodge 1/2 ton that was only in MPH and that what he used to figure out how fast to drive with the imperial system on the ticker. -----later DW.
