@Nou @cum_man @Alex_Fog @d0c40r0 @honkwerx @mushroom_soup Neither system is more precise than the other. The advantage of metric is that it's easy to convert units, and the powers of ten rule makes it to scale units.

But it also means that the unit scale isn't always useful for people. 'dm' 'cm' are not as useful of a scale as 'ft' 'in' are. The latter are based on human proportions, which makes it easier for us to visualize without a tool. It's why base lengths that were foot and inch like were so common around the world. 3 feet (m), 4 in (dm), and .4in (cm) are not as nice of a scale as yard, foot, inch. Metric has lots of issues like this, which is why even scientists are forced to invent non-SI units (ergs, barns, janskys, angstroms to name a few).
