1 KM is 66% of a mile, just as 1 Euro is 66% of a Pound ............ um, well ..... Does this mean that 1 KM is now about 80% of a mile? 2lbs is 1 kilo (nearly) - from old bags of sugar. I still think of baby weights in bags of sugar. 1 litre is nearly 2 pints - from bottles of milk. Temperature is Celsius, short distance in CM and Metres, long distance in miles (1500 metres = 1 mile-ish) I just about remember old money, but was 7 when the change over happened and so did both Imperial and Metric.
