It's a conspiracy - check your measuring devices

[k0ua]

3 teaspoons is 3x 1 teaspoon

ok so that maybe wasn't the best example in the world... but you get my drift.

Cook's magazine tested a bunch of liquid measure things for accuracy, most were wrong.

The metric system really shines when doing unit combinations or conversions.

Recipes in Germany (for example of metric) use weights more than volumes, so do many serious bread bakers in the US.

Sorry FG, all the science that keeps planes in the air is done in metric these days. There is a lot of metric use in the background, they just hide it from consumers so they aren't called EU socialists who are going to force you to speak French--the language of love, they say. :laughing: It's a crazy country we live in.

Yep.. thats why the Mars explorer crashed...

The USA does not really use the Imperial system of measurements.

In Jolly old England they use to use the Imperial system.
1 USA inch - Imperial = 1.25 USA inches.
1 Imperial gallon was 1.25 US gallons. Old gas cans use to be so marked.
Almost every American wrench would work, with 1 exception. That would be a 19/32's. common in England.
To the best of my knowledge the only American use for that size was the connecting Rod Bolt nuts on a model "A" Ford.

I'm in the go metric group. 10% of a foot is just no fun by comparison.

It takes a while to get a sense of how far a kilometer is, or how long 10cm is, but it develops eventually if you use it. I think that is part of the reluctance to switch, or maybe they are afraid they will be cheated because they don't understand the numbers very well.

The origin of the use of 12 , 16 or 20 in measures and currencies is thought to be that they lend themselves to even division of small quantities.

Twelve can be divided in half, thirds, quarters and sixths for example much easier than ten can.

Its easier to cheat in our system.. metric is all 10s..

Explain that to Grandma :laughing:

Wasn't there some US-metric snafu on the original Hubble mirror?

Back in the early 60's, when I started college, all of the science classes were taught using the Metric system. I worked in a research laboratory for many years, and of course we used the metric system exclusively. It takes some getting used to, and when you grow up with the English system, it's not as intuitive at first, but it's easier and better in the long run, and it's pretty much international.

I noticed when I was putting a mulching kit on my John Deere Mower, some of the bolts and nuts were SAE, some were Metric. Of course, all that is really needed if for the government to specify metric for all of its contracts/purchases.

My 20.32 cm Crescent Wrench is both metric and SAE while also being a darn good hammer.
