Something else I was taught years ago in the timber industry was that 1 foot (12 inches) can be easily divisible by 1/2, 1/3, 1/4, 1/6, etc. Any we all still use and talk in fractions even today. And when using fractions of an inch, you have the best of both worlds: imperial or metric, i.e. thousandths of inch, which is still common in engineering circles.
