hey!
very attractive website for students are online calculators or any converters, they are useful, because they have details of trouble with examples, that's why is very high possiblity to understand the problem that we wanna figure out.
for example this website explain: https://amazingconverter.com/length-converter/inches-to-feet
Our lovely wikipedia talks about inch, that it is (abbreviation: in or ″) is a part of length in the (British) imperial and United States customary structure of measurement. It is equal to 1⁄36 yard or 1⁄12 of a foot. Derived from the Roman uncia ("twelfth"), the word inch is also sometimes used to translate similar things in different measurement systems, usually understood as deriving from the size of the human thumb.
Also use of the inch could be dropped back where the 7th century. The first explicit definition we could notice of their part was once 1066 while it was defined as the length of three barleycorns. This was not a satisfactory research as barleycorn lengths vary normally. The British Standards Institute defined the edge as 25.4mm in 1930 in the paper "Metric Troops with Engineering: Going SI". In Advance 1932 the American Stock Company were laid to end in whether to take the same value (on any time the United states inch was 1/.03937 mm which approximated to 25.400051 mm). Because the estimates happened therefore bar, and also as Britain has previously descended on which spent, the ASA adopted that value in March 13, 1933.
this explanation maybe is not enough good for everybody, that's why we have other very polite of work websites :)
all the best
