I agree. If you want to, go ahead. Be different to the rest of the world.
Our kids can no longer learn their X tables and have to use a calculator for the simplest sums. Progress? No. Using fractions at least keeps the brain in gear!!
On a similar note: Fahrenheit scale of temperature was also a rubbish scale from word go. It was devised on the previous French(?)Reamur increment, but instead of zero being a fixed-forever point it was set at the lowest temperature they could achieve in the laboratory at that time (ice/salt freezing mixture). Pure water melted at 32 on that scale so you are stuck with a system of 180 degrees betweem ice and steam, instead of a nice round 100 for the metric system. The SI system is, of course related to absolute zero (no atomic/molecular kinetic energy, so ice melts at 273 K but at least the increments are the same as Centigrade (Celsius)
We have to remember the world was once flat (some still think it is), the Earth was at the centre of the Universe and the Sun moved around us (so the sun "rises" and "sets". What rubbish!!
We still say the sun has gone behind that cloud.
Little wonder our kids don"t understand science.!!
