the CCOHS (canada's equivalent to OSHA) doesnt specify on its site about units of measure, but its example of a data plate is only in metric
im going to assume its ok as long as the capacity accurately reflects the max rated load
call them and ask im sure the # is on the site

IE: if a 2500 kilo rated machine has a side shifter installed but the plate still reads 2500 kilo then the plate is wrong and i woulnt pass it
