silentpoet No you see 9.4 is smaller than 472. It is simple math.

Why should we convert to something the french invented?
I think 9373cc (or 9400 cubic centimeters) sounds more impressive then 'only' 572 cid. Even, rounded up, 9.4L (liters) sounds good.

Using all these things you can determine if one of them is straight to then use it as your guide for the other side.

Cool. Thanks!

We all can estimate rather easily what a mile or two is, but we have no frame of reference for km.

That's my problem with metric, anyway.

A kilometer is 6/10 of a mile, so 100 KM is 60 miles. There are 2.5 centimeters in an inch, so 5 centimeters is 2 inches. From there you can guesstimate pretty much anything. Those figures are not exactly accurate, but they're close enough for an estimate.

Brian,

Thanks. I've read a bunch of stuff you've written here. It's great, however my choices a while back make that not the best choice right now.

About 12 years ago I made the decision to replace the rusted through rear frame rail in my '66 mustang coupe. So naturally I attacked it with a sawall, then ordered a replacement rail. Yup... brilliant move on my part... first of many I assure you. So after 10 years or so (and several moves), I wanted to actually finish it.

If I was starting now and knew that the other rail wasn't tweaked, I'd just use that as a reference, but with it being moved (once with a front loader, thanks to farmer Ray), I'm not confident that the other hasn't been. I wanted to take the measurements, not only diagonally, but along the other axis as well.

Thanks,

Mike

cobalt327 I think someone earlier is confusing "metric" w/"decimal" (aka "base 10"). Our currency isn't metric.

Until the Euro, English currency was all fubar'd, as well as many other currencies worldwide. Compared to some of them, US currency is down right simple.

Developmentally, we humans go through a phase where language and such is easily learned. Once past that stage, it is far more difficult to learn/retain language. Maybe it's the same w/learning some math concepts like the metric and "other".

bentwings Yeah, well there are more women than men in the U.S.A. and no woman wants to have a rear end that's a 1000 mm or larger so it is ANSI for us.. haha

Settled!

Lets just say you work with what you got and conversion is not required. That really simplifies things for me.

JohnnyK81 Shhhh.. We'll switch him over to metric and he won't even know it!

Yep, guess I am just a stupid old man......Point is, that its hard to change what you have learned over the years, no matter how weird it is......They say that the English language is one of the hardest to learn because there are so many weird idiosyncrasies to it, but we seem to have it down pat. For a foreigner whos language has a set pattern to it, it is hell.

Another thing I have noticed about this subject...It started as a debate on 1/10s of inches and evolved into a debate on the metric system because, I guess on the base 10 aspect of it.........Not the same thing guys......

Temperature and speeds are not too bad....but this litres/100 km thing instead of miles/gallon ......makes no sense to me.

How many folks would have the same problem. Then you get into acres vs hectares on how many millions of property deeds which some politician would make into law on property transfer would be required to be converted to the decimal system. This translates into costs to people as well as state, and local offices as well as banks/lenders - and it goes on and on and on.
Can not or will not? I was trying to point out that we ALL use the metric system every day. Our MONEY is METRIC. Imagine if we bought gas by using fractions, would it cost $3 & 7/16 per gallon? So if it took 17 gallons that would be how much? 17 X 3 7/16 = ?
My first real exposure to the metric system was years ago when I was a deck hand on a tug boat. The other deck hand was a Belgian who had only been in the states a short time. He had been a captain in europe but his english wasn't good enough for him to pass his coast guard tests. He always spoke of distances in yards. Like the barge had 15 yards of space left to load. I finally figured out that yards are the closet to meters and that's how he converted in his head. I do the opposite now!
