I grew up with Imperial measurements, but metric make far more sense.
Yes they do. Metric is divisible by 10 on everything, so easy.
But the UK still does both (randomly). And we are used to doing it so it isn't a problem.
My industry is a good example of how nuts it all is. I work in the refrigeration industry. 'Fridge' copper pipe is always measured in inches. Always. Plumbing copper pipe is measured in mm. The two are not compatible.
All the equipment this imperial copper is connected to is measured in kW capacity. Except if it's American equipment, which is measured in BTU capacity. BTU stands for British Thermal Unit. We invented the measurement but only the Americans use it now (we don't).
So I buy refrigeration equipment (unless it's American) with capacities measured in metric (kW), but all the pipe connections are in inches.
Pressures in my industry are always PSI, but we often have gauges that only read BAR.
All temperatures in my industry are measured in celcius, except the Americans still do everything in fahrenheit. Then we also use Kelvin as a temperature scale, which is even more confusing.
So for forty years I have had to work in Watts, kW, BTU, inches, mm, PSI, celcius, BAR and Fahrenheit all together on a daily basis.
Oh and vacuums are measured in inches of mercury. Or mm. Or torr.
And I buy screws in mm diameter and inches in length.
No wonder I'm mental.
