Gonna jump in here for a minute, well....coz I want to.
Re: Measuring stuff....
Depends on the generation, to what measurements are used.
See, my parents generation still talk in foot and inches and pounds.
My generation tends to talk in a combination of both. Guess that comes from having the metric system fairly new when I was at school and having parents/siblings that talked *old school*.
When I think of height, I always use feet and inches, but I know my metric height.
My nephews and neices are always *what's a foot in centimetres?"...I guess they are metric only.
Way off topic, but you get that.
