This was going the rounds not long after decimalisation.
A guy goes into a woodyard.
"I want thirty-two feet of timber."
"Sorry sir, it's all metric now."
"OK then, give me ten metres."
"Ten metres you say sir?" Says the assistant looking at his tape measure.
Hmm....
Ten metres....
hmm..
let me see,
that's about thirty-two feet isn't it sir?"
Even now I can go into a woodyard and order timber in either Imperial or Metric, they have sophisticated cutting machines that they can imput either in its computer.
