I grew up with metric.
Both metric and imperial (fractional) are just as easy once you learn them.
True, imperial takes a little longer to sink in, but once it sink in that is half of half of half it can be easier than metric for some things.
Do you have problems with the 12/60/60 set up of clocks? I'm sure you don't.
The SI system is rooted in science, whereas the imperial originates at places more ancinet than that at in cases it relates to humans.
100F supposed to be the approximate normal temperature of a human body.
1 foot is the approximate length of the feet of a grown man and divided by 12, like the months of the year or one half day it results in an inch, which is the approximate width of a grown man's thumb.
1 yard is the approximate length of a grown man's stride and by striding did they used to measure land, or yard.
Normal heart-rate is about 60 beats per minute. So muliply it by itself and you get an hour. The division of the day by two times 12 has more to do with astrology and the movement of the earth, but it is nice to know that it is connected to humanity.
A pound is the weight of 7000 grains. The measurement of 'grains' is the average weight of a common - not genetically manipulated:lol: - wheat grain.
...and so on and so forth.
