How else you split it up is neither here nor there, but it is the length of the second that is the deal breaker. Change the length of the second and you lose Meter-Kilogram-Second relations, all your SI units go floppy and all the physics and engineering that used to get done with them gets harder and crunchier; your direct equivalences are gone and it would be as bad, worse, as working in foot- pounds. The second is the key part of the system you absolutely need to keep.
100% true - but if we make the switch before SI units are introduced?
