I've been doing some a little poking around the web. Apparently how some of the other metric supports would change things to metric, specifically
focusing on road signs, is to erect new metric street signs but keep them covered. And then on one day reveal all of the signs.
Anyone remember old British pounds? They used the pound, the shilling, and the pence. There were 12 pence in a shilling, and 20 shillings in a pound.
This made 240 pence to a pound (not like the Dollar or the Euro, depending on where you live, which are both decimal - the same number system with
which we count). To make matters worse, they had all of these weird coins that were not related by tens. For example, they had the farthing, which is
1/4 of a pence, a halfpenny, which is 1/2 of a penny, a florin was 2 shillings, a half crown was 2 shillings and 6 pence, etc.
Here's a fun math problem. John weighs 20 stones 3 pounds and 6 ounces. His father puts him on a diet promising to pay 1 sixpence for every ounce
John loses. After a fortnight John weights 18 stones 12 pounds 11 ounces. His father only has guineas. What is the smallest number of coins John
can give his father in change? If John lost the weight through exercise by running 200 furlongs, how much money per rod did he earn?
Old British Pounds work the same way the English system does. It uses weird number bases like 12, 16, 1,760, 5,280, etc. Metric uses base 10, the same
system we all count with every day. Take, for example, a foot, which is 12 inches. In a decimal system, the numbers start counting over at 10, which
we're all used to. But in a foot, the inches start counting over at 12. This makes converting by shifting the decimal point impossible.
