Was watching an email list discussion about imperial vs metric.
I’m young enough that all I learnt at school was metric, but most of the adults around me (such as my parents) were more familiar with imperial, and some of it rubbed off and entered my knowledge and vocabulary.
So I do know that an adult male is about 6 feet tall. That railway lines (in Victoria) are 5 foot 3 wide.
Computer monitors I know in inches, and some TVs, but I can’t quite grasp how much smaller my 19 inch computer monitor is compared to my old 68 cm TV.
Airlines refer to altitude in feet and yards, but otherwise all long distances to me are metric. The only reason I know about miles is that they are roughly
1.4 1.6 kilometres, and a yard is just under a metre.
The weight of newborn babies still seem to be more commonly referred to in pounds, but I have no concept of imperial weights apart from that; it’s all grams and kilograms.
