I'm proud of you?

Presumably you can also read the official BIPM SI Brochure. As mentioned, it will tell you the same thing:

  >if you want to dumb it down to the public you might as well go in miles per hour, leagues per day, etc., spaceflight is not the place where it is appropriate.

1. Quick, call the spaceflight units police.

2. When you ask the regular units police (BIPM), their official decision is that hours are "accepted."

I trust you can read the dictionary definition of "accepted" all on your own.
