Nobody uses fractions in the USA for small measurements, either.
Typical machinist measurements are in thousandths or ten thousandths of an inch. )
Engineers and surveyors often use feet and tenth of a foot.
Even carpenters don't always use standard fractional inches. A framing square has rules divided in 16ths, 8ths, 10ths, and 12ths. Use the most convenient.( a quality framing square also includes an inch divided in hundredths)
Brick masons course their brick in fractions of a foot. Their rules have divisions for 3,4,5, and 6 courses per foot.brick are sized so the brick and mortar joint come out even.
One of the beauties of feet and inches is there are lots of factors in the system, making it easy to divide something into equal parts, you can divide a foot into halves, thirds, quarters,sixths, and twelfths with no maths and whole units. Eights involves trivial math. With the inch using 16ths your odds of finding even divisions increases.
A meter or centimeter has only multiples of 2, 5 , and 10 as even factors.
The Elizabethans weren't stupid when they adopted the system. There is a reason the mile has 5280 feet in it. Try factoring it.
