If one has trouble remembering what various metric units mean in English measures, there are websites that will do conversions. I am old and forgot a lot of stuff, so I have those sites bookmarked for when I just can't recall the math to convert metric into what my old brain uses.

If we just switch and educate kids with metric system, it will be easy for them AND it would help US manufactures compete in world trade.

This 'executive order' is just more foot dragging AND enabling drug sellers/users to avoid throwing out an archaic and less accurate system of measurements. Guess all the drug traffickers Trump knows (and pardons) are old school thugs.

Nobody will be able to figure out how that works.
