You know what other measuring system is based around highly composable numbers?
It's not metric. It's the imperial system. Halves, thirds, quarters are all neat numbers. It does get a little weird because we only use feet, yards, and miles today, but there is a progression from inch to mile that all make sense to some degree.
Similarly with volumes. You can get from teaspoon to gallon without having to worry about any weird decimals.
The only thing metric really has going for it is uniformity of conversion.
People shit on it, but the imperial system is not actually that horrible.
