What next you are going to ask how many inches in a mile? Those are two units that aren’t used in the same context. I’d be like if I asked you how many seconds are in a year. Or if asked you how big a notebook is in kilometers, rather than in centimeters.

A hybrid system really isn’t as wild of a concept as it sounds. We already just use conventional time keeping, metric is largely forgotten because of how unhelpful it was. metrictime.info

Doesn’t mean you have to take all of the weird units and conversions from imperial but it means to cherry pick the best of both worlds so we have a system that just works with what real people use it for.
