We were brought up on Imperial or "English" as we called it back then.
Then we changed to decimal currency before I left School and this new SI (Metric) system was coming in so we learned in bits and bobs about this new fangled system of measures and were fairly fluent in both disciplines. We could even do arithmetic in our heads or on the back of paper bags with a pencil.
the 12 times tables were king.
we even knew what farthings were too and you`d always know somebody who actually had one
