Our road signs are in Miles and MPH, as are our car speedometer/ odometers
Our milk comes in pints, as does our beer
We measure ourselves in feet and inches, our weight in stones and pounds
I grew up after the so called metrification but I have little concept of a kilometer, except that its too small to measure walking distances conveniently in...
I know a liter is too much to drink, but a pint is just right if I'm thirsty
I know im 6ft tall, whats that in mm ? 1828mm? how is that a more convenient way to measure my height?
I weigh 13st 2lbs I know thats not fat, maybe I could lose 1 or 2 lbs. I dont know what that is in kgs
I know a pound bag of flour is a reasonable handful, whats a kg of flour? 2.2 times that? I dont find that a very convenient measure
I know a yard is about 1 step, a meter is a bit more than 1 step but much less than 2 steps... not very convenient
I know a yard is split into 3 feet, which are very convenient to measure mid size distances in, a meter is split into 100cm which are so small I have to use more than one to measure the width of my little finger!
In the real world we use imperial measures because they relate to real life, thats where they came from, rather than metric which originated in a science lab.
What I do know is a long list of conversions to convert things that are in metric back into a measure thats meaningful!
1.6km in a mile, 26mm in an inch, 3.3 ft in a meter, 2.2 lbs in a kg, 30cm in a ft, 568ml in a pint...
