I once complained to the BBC because many of their radio programmes use US dollars and not pounds Sterling. There is some logic to it though, that around the world people know US dollars better than any other currency.
I read something about a driverless car topping a driverless car speed record in Germany. Australia and Germany are countries that officially uses metric measurements, yet the article must have been lifted straight from a US publication as the speed was given in miles per hour with the kilometres per hour in brackets. Get that? In an Australia publication miles were used when talking about car speed when we use metric from another metric country. There is no logic to that at all.
As I have mentioned before, I am greatly concerned at the backward steps we have taking with metrication. We are back to pounds per square inch in tyre pressures, pounds and ounces for babies, calories for food energy, brake horse power for car engines. Sizes of tv screens and computer monitors have gone backwards with most now talking in inches. These are tvs being made in metric countries being sold in a metric country ant he screen size is predominately in inches. Metricating the length of a Subway roll, 6 inch or footlong, is perhaps unreasonable, and eight inches will always be a respectable figure.
There used to be some sort of government metric authority to promote metrication and help people understand it. I wonder if there are any remains of it in some government department.
