Conversion refresher: 1 inch = 25.4 mm 1 inch = 25,400 microns 10 microns = 0.3937 mils 10 microns = 0.010 mm so 0.4mm = 400 microns and for s/n/g: 1mm = 3.240783e-20 parsecs (pc) Have some fun with that one!

I have always gone with blade length equal to board width plus 2 inches - 1 inch either side. Is there any technical reason that I could not use a longer blade, say 2.5 inches on either side?

in both samples the water displacement is 1 cubic inch of water since the volume is the same. the first has a thickness of 1 inch, the second has a thickness of a few microns. if you know the volume and one of the lengh, width or thickness, you can c

Settting up conveyors for a SMT line....

Most conveyors are sold by the inch. I allow for no more than one inch gap between the end of the conveyor and the next piece of equipment. If you trust your measurements, 1/2 inch is best. This will allow for the smoothest transfer possible of small

1 us gallon = 231 in^3 (NIST) 1 inch = 2.54 cm 1 in^3 = 16.38cm^3 16.38 cm^3 X 231 = 3785.41 cm^3 1cm^3 = 1g (pure water) 3785.41 cm^3 = 3785.41g or 3.785.41Kg Do I get credit for showing my work?
