Martin Vlietstra looks at our counting system and explains why we count in tens and not in twelves. Our counting system and the metric system are both decimal based (i.e. they use base 10). The entire metric system is based on tens and powers or ten, which fits in neatly with our counting system and makes calculations easy.

Tenths of a mile on UK odometers relate to nothing on British roads
Odometers in vehicles measure distances travelled in tenths of a kilometre or tenths of a mile, depending on the unit used in the target market. A tenth of a mile is 176 yards. However, there is nothing on British roads that is measured by tenths of a mile.

If the current Government implement their proposals to remove the requirement to use metric units for trade, it will be the first reversal of metrication in the UK and probably the first reversal in Europe since the days of Napoleon over 200 years ago.

After celebrating the arrival of decimal currency in the UK 50 years ago, Metric Views now goes back to basics on decimal measurement. No, we shall not be looking at nautical distances or Gunter’s chain! Continue reading “How metric units fit together”
Whitworth’s forgotten legacy
Whitworth is famous for the eponymous screw thread, and for his promotion of standard measures and interchangeability that brought about an engineering revolution. Less well known are his enthusiasm for decimal measurement and his opposition to the introduction of the metric system in Britain.
Should we forget fractions and only use decimal?
I am motivated to write this article because, in the past, I have come across supporters of metrication, some of whom with teaching experience, who say that only decimals should be taught rather than both fractions and decimals in elementary mathematics in school.
