That’s what I am. Even though I was born WAY after the crossover from Imperial [inches, pounds, etc] to Metric [centimetres, kilograms, etc] I still mix my metrics.
Why?
Well, I was raised by parents who grew up on Imperial and still carry around a little slide-rule thing so they can convert Metric to a system they understand.
I usually measure people in Imperial when it comes to body measurements, but I use Metric for weights.
It’s all rather confusing, really.
