Not that the metric system doesn't have its own moments. Consider the standard for determining the metre length unit.
The basic unit of length in the metric system; it was originally planned so that the circumference of the Earth would be measured at about forty million meters. A meter is 39.37 inches. Today, the meter is defined to be the distance light travels in 1 / 299,792,458 seconds.
Based in science? Yes. Intuitive? Not hardly. I like the definition of the kilogram better:
The kilogram is almost exactly the mass of one litre of water.
Consider, by contrast, the definition of the inch:
The old English ynce was defined by King David I of Scotland about 1150 as the breadth of a man’s thumb at the base of the nail. To help maintain consistency of the unit, the measure was usually achieved by adding the thumb breadth of three men—one small, one medium, and one large—and then dividing the figure by three. During the reign of King Edward II, in the early 14th century, the inch was defined as “three grains of barley, dry and round, placed end to end lengthwise.” At various times the inch has also been defined as the combined lengths of 12 poppyseeds.
Makes one pause when considering the implications of having a 427 cubic inch engine in your car.?
