Micron to Inch Conversion

I have always had a hard time understanding the CMM Calibration Technicians who have serviced our CMM's over the years because they speak in terms of microns and I speak in terms of inches. I have done some research online and I think that I have figured out how to convert from microns to inches, but I would like a verification from anyone who knows for sure. Below is the conversion equation that I have come up with after doing my research.

1 micron = 0.0254 inches

Is this correct?

No:

1 inch = 25,400 microns so,

1/25400 = .00003937 inches

Re: Micron to Inch Conversion

Just type "convert 1 micron to inches" into the google and you get "1 micron = 3.93700787 × 10-5 inches"

And it does many other units as well. Like "convert 1.23 btu to joules" gives "1.23 btu = 1 297.7187 joules".

Re: Micron to Inch Conversion

You know, I did do a search on Google and I saw the conversion amount displayed, but at the time I didn't realize that it was giving me the answer in scientific notation!

Re: Micron to Inch Conversion

It's amazing how easy to overlook things that you are not watching for! I do that too sometimes When the context isn't right, your mind just skips right over certain things.

A classic example is this little video. http://viscog.beckman.uiuc.edu/grafs/demos/15.html

Watch carefully and count how many times the white team passes the basketball. How many did you get? Did you see all 14?

Now just watch it in general...

Re: Micron to Inch Conversion

Speaking of mathematical notation that can leave the casual observer going, "Huh?" I recall the very first time I encountered the symbol for a factorial (!) long before my high school math caught up. I remember clearly thinking back in the 50's, "Wow! This must be something special if they put an exclamation point after the number!"

To make matters worse, the teachers I had at the time had no clue, either.

It took an uncle who was an aeronautical engineer to clue me in when I casually mentioned I had seen this in Scientific American.

FYI
An excellent tool for your toolbox (PC) would be Prokon.
Their unlimited site liscence (when I bought it ) was less than \$150.00
Its now \$203.00 and worth every penny.
