The absurdity of the use of kph

  First and foremost I apologise (yet again) for such a long gap in between blog posts. The return of freedom over the past year has kept me away from screens. They say it takes 66 days to develop a new habit.

For the most part, metric measures are based on an SI base unit, with sub units which are either a multiple or a fraction of ten of that SI unit. A simple example of this is the metre. It is the SI unit for length. A millimetre is 1/1000 of a metre and a kilometre being 1000 metres. However there are some exceptions. With mass, the kilogram is the SI unit, rather than the gram, but still, all measurements of mass are still based on ten around the gram. I am sure none of this is new, but I will get to the point eventually. The SI unit for time is the second. It is common for SI prefixes to be used for times shorter than a second (millisecond, nanosecond, ...
