History question: mixing mm and inches

[PariahZero]

So it doesn’t surprise me to see both the Metric and US Customary Systems, since it’s a global game with a long history.

It does, however, surprise me to see most US cues using mostly US measurements - oz. inches, etc.

Except for the tip diameter, which is in mm.

Is measuring tips in mm a recent change in the States? What was used before then in the US? (16ths? Caliber? Thou? Beard-days?)

upgrading one's tool box is really not something to look forward to

Many decades ago the French were providing the most popular tips and they were measured in MM. My guess is cues were made to match their tip sizes and when the Americans started making tips they stuck with the previous standard.
