15MM Tap......Drill Size

[Yondering]

Why is that? Does converting my final fractions into decimals provide an incorrect answer? Or do you disapprove of my indulging
in some fractional masturbation?

I'm curious too. Paul, are fractions just a problem for you, or do you have an example where that method doesn't work? All the combinations I tried match the tap/drill chart pretty close.

NONE of my machines have fractional dials on them.
I for one are real glad we left all this behind when we adopted metric.

What does a dial on your machine have to do with a tap drill size? None of my machines are fractional either, and they aren't metric.

yup, one of its many redeeming features

There, fixed it for ya. The only problem I have with metric here in Canada is that we didn't go all the way in the 70s. In
order to "fit in" with the States we only adopted parts and now we're stuck with this bastardized mess we have today
that mixes metric and imperial. The only light on the horizon is that my grandchildren are being taught only metric so in
another generation or so we'll finally be able to clean up this mess...

...wehich lead to my writing a computer program in Fortran (THAT long ago)...

I took computer programming in tech school in 1966 and 1967. I used to love programming in Fortran. Haven't had anything
to do with it in many years so I don't know how it has stood the test of time but back in those days it seemed so logical and
simple to use. We ran it on an IBM 1620 and the data and program could only be input with punch cards. I'll always
remember that I had far more problems getting the program onto the cards than I actually did in writing it...
