Ah yes the old measuring systems problem. I think you are right but is that British ounces or American ounces or did we have the same ounces, just different gallons?
You( not you personally but the U.S.) used to laugh at and quite rightly so or at best regard as quaint our old British currency which was 12 pennies in a shilling but twenty shillings in a pound so 240 pennies in a pound with the good old "half-crown" thrown and of course we had guineas in which we paid our legal profession and our tailors for good suits. There never was a guinea coin of course. It was equal to 21 shillings. Why?? ( see witch burning for the logic)
Imperial(is that from when we had an empire?) and U.S. measurement systems really belong to or should belong to the era of bubonic plague and the odd session of witch burning
I now think in terms of centigrade but it was a long hard road to get there. We need to relieve our kids of such suffering. Never getting access to the destructive drug of imperial measurement is better than years of "cold turkey"
