Generally we've settled down into where we are. My year was the first to be exclusively taught in metric, and my memory of old money is from picking up the discussions when we went decimal (quite odd that I sometimes have to tell people older than me what a sixpence being half a shilling meant).
So it's stones for weight, feet'n' inches for height, and metric for the rest with the exception of miles and pints.
Having had a sting in metrology (one of mankinds earliest sciences 😀) it's a shame the UK didn't take up metrication back in 1897 when it was proposed. Mainly in order to catch out the permadim who would persist in thinking it was somehow "new" in the 1970s.
Today, I am mainly grumpy.😠
