I think it's about as relevant as rods perches and bushels!. I don't see the metric system as foreign just a lot more sensible like decimalisation. There are some measurement systems that aren't metric but make sense the only one I can think of is nautical miles in navigation
Given a choice, I prefer the good old hundredweight (cement bag) unit.
MTPLM just under 89 cwt, payload 13 cwt approx.
I weigh about one and a quarter cwt.
