@jimgoodall @vwbusguy @saramg Out of curiosity, which construction measurements are metric?
We had a reno done recently, and decided our ceiling heights in feet, all the studs remain 16" on-centre, etc.

I'm old enough to still weigh myself in pounds (vs. the doctor weighing my daughter in kg, requiring my using a calculator), still use F on my oven, and had until quite recently, for decades, thought I was six feet tall because my driver's licence says I'm 180 cm.
