Metric

Many of those who grew up with feet and inches can use either. Those who only know metric, only know metric except for miles.
How tall a man is is a good example, Wellbeck. If I have an image of my 6 foot tall husband in my mind, then saying 2 m means I have to deduct 6 cm to get the same image. Although I suppose I could say he’s just under 2 m tall or even he’s 194 cm tall.

Metric and imperial measures have both been used, sometimes simultaneously. On a building site it is not uncommon for a builder to ask for "2 metres of the 2 by 3" (meaning 2 inch by 3 inch timber).

In spite of having learned the metric system well before 1965 when I studied science, I still find it easier to visualise my height in feet and inches, my weight in stones and pounds, drinks in pints and a field in acres.

These days thanks to google, it is no problem to switch from one measurement system to another .

I can turn a blind eye to my weight in kg but when it’s given in stones and lbs I am horrified!
Same with baby weights- 7lb 6 all of mine but no idea what that is in new money!

no it's not.
i think in feet and inches.
am aware of metric and use it when necessary, eg technical items, medical matters.
but for everyday things, it's always, he was a tall man, at least six foot.

Yes. If anyone has not got the hang of metric by now, then I just don't know what to say!
