Standard and Metric -- I play for both teams!
Edward Damewood, Northern Alabama
>Well, I resisted yesterday on the standard and metric topic, but I have succumbed now and I'm drawn into the fray.
The thing is this: I'm an engineer by profession and a woodworker (occasionally) by hobby.
At work, it just plain wears me out to have to convert units to feet, miles per hour, and so forth -- because the units and conversions are so darned inconvenient. I can easily do a lot of math without a calculator when the units are metric, because I have all of those powers of 10 to work with. That's quite convenient when I'm sanity-checking a computation and I don't have my RPN calculator handy (geek alert!). The multiplies and divides are much simpler that way, for the powers of ten add and subtract out of the exponents. At work, give me MKS or give me death!*
That said, I am just as adamantly in favor of using inches (and nice binary fractions of inches) when I'm working on some sort of home project.** Now, why is that? (I'm wondering, too.) Well, for one thing, I like the variety of unit sizes it affords me -- quarters, eights, sixteenths, as opposed to different chunks of mm (7, 3, etc.). You may not buy this, but, for me, generally the mm is too small and the cm is too big in doing my little projects. I like to be able to estimate by cutting in half, too. But, I guess the main thing is that typically the math that I am doing on these home projects is just addition and subtraction -- and the power-of-ten conversions that make the metric system so much better for me at work basically do not play. Adding or subtracting fractions here and there isn't that big of a deal once you've done it a few times.
Heavens to Betsy, I need to stop. I hope I have not been offensive.
I haven't read all the threads that are going right now, so please pardon me if I've repeated things that others have pointed out. But, most of all, please pardon me for this endless babble.

* MKS = meters, kilograms, seconds -- a biggish flavor of the metric system
** And I'm good with feet for some sort of construction project (e.g.) where the number of inches becomes unwieldy.
