You've just been plonked, err, I mean plancked.

It's not. But when DESIGNING in metric, everything is done in tens or tenths, hunreds or hundredths. So 1MM is .01CM, none of the silly 12 inches to a foot, 3 feet to a yard, 36 inches to a yard etc, and none of the .125 inches to the 1/8 inch. You design to the .1meter or .01meter, or 12.5mm or whatever and never need to convert by anything more complicated than moving decimal points to convert from one unit to another.
He did, and he blatantly overlooked the metric RCH. Ptooie, how many thou was that?

It only happens when I'm matching board lengths and I measure the first board. If it lines up precisely with the metric side of the tape and is in between ticks on the imperial, I use the metric scale. Not a prob.

Ok, but why would I WANT TO do that??? It's damned difficult to eyeball 2 mm vs 3, But dividing spaces into successive halves is easy. I can reliably estimate 3/23" Half way between 1/16 and 1/8.
Call them silly if you want, but I'm not buying it as long as Greenwich runs on base 60/60/24/30,31,29or maybe 29.
Although I have to admit getting away from pounds/shillings/pence/ha'pennies was a good idea. Shame it's not working so well.
I do that one too. But I wasn't going to admit it first...
AND! Even the type is so obvious anybody would catch it. That's not so obvious in mm.

Don't worry, we'll just use nanometers, micrometers, or maybe picometers.
If we wanted to really confuse things, we could apply the SI prefixes to inches.

It is. Working with wood and present dimensional material is not, but designing a new machined part is a snap. If you start with rough lumber, you can plane it to 19mm easy enough but with a 2 x 4 you'd be off .1 from a round number. 38.1 x 88.9
Designing a new part and new machined tool, metric is a snap with very few less than full mm dimensions.

Unfortunately, it is also wrong, or at least inaccurate.
1 mm=0.1 cm, not 0.01 cm. For woodworking, 0.525 mm is the same as 0.5 mm, or 0.0206692913 inch, or however many in fractional inches. 0.525 mm is orders of magnitude different from 3/8".Puckdropper wrote in news:4f39ef8e$0$5486 $c3e8da3$ snipped-for-privacy@news.astraweb.com:
That would then be Silly Itsy SAE ...

On the other hand, lumber being very anal retentive in nomenclature, width x length in mm of sheets of plywood, wallboard, or whatever is really interesting 122x244cm

With metric measurements, exact size should be easy, right? Do the manufacturers still try to sell 18mm plywood that's only 17.2mm?

Do they still sell 1 lb coffeecans with 12 oz of loosely ground coffee?
the two 12 footers that my dad had my whole growing up were metal cased. I remember him buying replacement tapes for them several times. I'll bet he still has them somewhere in his array of stuff.
After working with non retractable measures for the past 6 weeks, almost exclusively except for when I needed to measure more than 48" I have almost given up on tape measures. Too inconsistent and finicky.
I probably have 5 FastCap measures. IMHO they are as good asthe next measure. I too would like to see a smaller tape measure, 12' would be nice. I tried a
I Fast Cap I prefer the green lefty/righty / measure in imperial.
Oh! API would be automotive too.. LOL
Yabbut, the term "RCH" has such a wonderful je ne sais quoi about it.
How about using "portions of a parsec"?

And on some tapes, 2 little sticks is 1/5". That played hell on a buddy and me when He was calling the measurement, from his new 1/10" scale tape to me, so that I could cut the exterior window trim for him to attach on the second story. Still Too LONG!
