Imperial measurements are total nonsense and have no place in the modern world.
The only thing that makes even less sense is how the US try to decimalise their imperial measurements! -"1.6 inches"- 'WTF is that??!!' I hear myself scream at Adam Savage on Mythbusters almost every episode, generally followed by "You cannot decimalise measurements that are not based on units of 10, you numpty!"
This is not anything new [ or have I missed something] When I was at school back in the 1950s we were taught the imperial system with fraction and decimals ,
An inch could be divided into 1/4 , 1/8, 1/16, 1/32, /164, and so on and each fraction had a decimal equivalent
so 1/4 = .25 , 1/8 = .125 , 1/16 = .0625.
In the building industry I believe fractions were used rather than decimals , however in aircraft engineering decimals tended to used rather than fractions
The other common way an inch was divided was by 10 so 1/10 of an inch = .1 1/100 =.01 and 1/1000 =.001
Now in engineering 1/1000 was commonly used to define the limits of a measurement but was stated as a decimal
Thus the size of the block say was 3 inches +/- .005.
Therefore there is nothing new in describing an imperial measurement as a decimal
Now going back to my school days we were taught the metric system as something we needed to understand but we never had to actually use it to work out problems. So what do I use now as the metric system slowly over takes the imperial system
Well in liquid measurement I still think of pints and gallons because I have got used to them and can imagine what it looks like. I can work in metric but it would be as a multiple of the imperial measurement
Weights the same as liquid
Distance miles wins, but when doing say woodwork DIY I tend to use the metric system , but when I am talking/ doing engineering I tend to use Imperial because that is how I was trained
Now my children when at school in the 70s and 80s were taught using the metric system and taught the imperial system as a side subject and I would think now they are not even taught the imperial system. Eventually we will I sure adopt completely the metric system but it will be easier when old codgers like me have gone to their 2300 mm by 700 mm coffin
or is it 90, 35/64 by 27, 1/2 inches which can be written as 90.568 by 27.5 inches
A question for you though is why have we not adopted the decimalization of time . For instance we could have
100 minutes to an hour, 10 hours to a day, 10 days to a week etc. I understand the French did this during their revolution but it was not popular with the peasants as they still only got one day off a week which was now 10 days rather than 7
