I cant even reach for a calculator because the resulting decimal wont mean a damn thing on this 16th degree tape measure...

For the record, I CAN do that math easily, Im not a moron :p but its not a natural way of thinking for someone that is VERY familiar with base 10.

I learned fractions on paper but I have always been a visual person. Maybe people who use a tape for living (me) have a different perspective?

It would've taken me all of maybe 3 seconds to figure out 9/32 from 3/8 in my head.

Cpl things......

We have a pretty full compliment of both systems....and I mean,"all the way"(machine shop/metrology lab).So the following is NOT because of any lack of equipment or talent to use thereof.

There is a huge difference IMO,in the speed at which a metric tape and an Imperial can be read.BUT,I can't explain it very well.You need to work in either the siding(real wood please)biz or as a trim sub.Both of these professions are at the limit to how fast a tape measure gets used/read.

If I handed you both system's tapes,you will....by about lunchtime be using the std,non metric tape.It's how well,....which translates to speed,that your eye can resolute numbers.Think reading a wrist watch.Your mind already knows where all the numbers are,so you glance and you know what time it is......very quickly.

That sort of happens with a tape.The metric tapes drop the ball here.They're slow as dog***t.

Next up,check out a "real" framing sq sometime.Ever wonder why it has 12th's and tenths/hundreth's on it?Not all measuring systems work ideally for all applications.To the point that I prefer metric in several areas......but not on a framing sq or a tape measure.But as usual,YMMV.Good luck,BW

Those who say it cannot be done shouldn't interrupt the people doing it.

For me it wouldn't matter much-I can make an error using either system!
