The base 60 part of time is the least-used part of it. Very few people care enough about exactly what minute or second it is and end up rounding it to the nearest 5 or 15 anyway.
The people who do care about having precision in seconds usually aren’t converting it to minutes or hours.
The nearest 5 minutes is a 12th of an hour, the nearest 15minutes is a quarter of an hour. No one ever cares about a 10th of an hour (6minutes) i.e. the nearest minute or second so you inadvertently demonstrated my point. Also the “high precision in seconds” is also conveniently a base 60 system which also goes evenly into a full day, or week, or year despite none of those measurements being metric either.
What about time? That’s base-60, and one of the most useful measurements we have.
