Mandating the metric system
But the contract for Orion, the manned vehicle intended to replace the Shuttle, was awarded to Lockheed Martin, at least in part, on the understanding that all engineering would be submitted in thousandths.
That measurement units need “context” for meaning, and are chosen depending upon the given circumstances is nonsensical.
Ours is in complete decay, yet you celebrate this fact.
There is no “seamless transition” between metric and our non-system.
What possible context makes the measurement of human feet require barleycorns as a unit? You cite examples of multiple units which are in use and describe the same quantity as something wondrous which we should lionize.
This is not an advantage, it is a called unit proliferation.
