Yup.
England where nothing even remotely looking like metric had ever been heard of till the mid 70's
I grew up with Pounds, shillings and pennies as the local currency.
12 pennies to a shilling and 12 shillings to a pound.
Decimal? What the F*&^% is decimal supposed to mean? That's what most of the population thought when they converted to the new monetary system. (somewhere around 1970. Can't remember the exact year as I was about 6)
Overnight, prices trippled, quadrupled in some cases.
A chocolate bar that used to cost Threpence (3 pennies) in the old system suddenly cost 5p in the new system.
5p is the equivalent of a shilling in the old system and as a shilling = 12 pennies, this is a four fold increase.
It was way too complicated for many people to convert easily so the unscrupulous ones who could simply ripped everybody off.
This process severely f*&^ed up my childhood and the economy of England took years to recover.
Incidentally, England still uses miles and although the official unit of weight is the kilogram, you would be hard pushed to find a single marhet trader who doesn't sell meat, fish and veg by the pound. I don't believe this will ever change because the English are stubborn bastards.
