Having been schooled in imperial measurements with metrication coming in du
ring my student days, I tend to use both, imperial where I need to divide l
engths in halves, quarters or eights which in metric soon ends up in measur
ements needing to be calculated and often involving fractions of a mm.
In defence of schools teaching only metric measurements, imperial is going
nowhere so why teach something that will only add to confusion. After all w
as it not NASA that missed Mars because someone mixed up imperial and metri
c, so if some of the top scientists and engineers can confuse things what c
hance have kids got.
An awareness of imperial is needed but only in those areas of work where le
gacy products exist and in those cases it is beholding on the industries in
volved to train their operatives in the skills required.
