Well, the major stumbling block to metric system in the US has been addressed, Finally, and in perhaps 50years it might happen.
When I was in school when they taught metrics they taught a bunch of totally useless stuff like how many inches in a meter or 5/8 of a mile in KM, or 5(F-32)/9=C and such.
Now fact is, if the US goes metric, I need to know absolutly NONE of that
Today they teach "How long is this line" or How much does water in this jar, or how heavy is this brick.. and they provide you with the measuring tools, and you have to measure it.. This is good
I mean, Here is MY course on metrification:
Lesson one
How many pennies in a dime? Dimes in a dollar? Dollars in a ten-spot? Ten-spots in a C-Note? C-notes in a Grand? (hint all answers are TEN) That's metrics
And every drug dealer from here to there and back again.. Understands those metrics.
Lesson 2:
You are going down the road and you pass a sign: Speed Limit 40
You look at your speedometer.. Needle is nailed, on 60
You glance in your rear view and there he is.. Officer Smily.. Big Simle, Overhead lights on, Pointing to you and to the curb.
WHat is about to happen?
(HINT: Ticket for 20 over the speed limit)
QUESTION: KPH or MPH? (Answer: Does it matter?)
And that's all you need to know about metrics.
Today they teach that way... Which is a good thing.. I've been teaching that way since about 1970.
Oh, did you know YOU are metric? Yup, what's normal body temperture..
Well if you take that math formula I posted up above 5(F-32)/9
98.6F = 37.0C
