Hi Gang,Need help in converting units between english and metric. I have had this trouble ever since we swithced units at my pre-retirement job.Couple of years ago while still working I had this handy little FREE program on my laptop. It is an excellent tool to have running when you are working in gmax and you know the wing span is 49.65 feet and want to convert that to meters. Better yet is when you have 16.375 inches and need to convert it to meters. It will even help you in converting 2 fortnights into 28 days!Get the FREE "CONVERT" from http://www.joshmadison.com/software/[email protected] us make it better!http://mtco.com/~rsam/fartslogo.jpg11/23/02

"Convert" is a handy program. I haven't seen it in a while, or since the last time I worked.The only thing I ever bothered to memorize is 1" = 25.4mmFrom that, you can convert back and forth, inches, feet, miles, meters, kilometers, whatever, as long as you understand the system (like how many feet in a mile, how many mm in a cm, and so on).As an engineer, I always liked designing in metric. I hated fractions.John Woodward

When we started 39 years ago we were beyond fractions of an inch. We used decimal parts of an inch. Yes, we used nice direct conversations like .375 for 3/8 and .406 - 13/32 for the clearance hole for a 3/8-16 bolt (yes we used fractions for thread sizes).Quick -- What is the clearance hole for a 8mm bolt?Now lets see, how do you use 1"=25.4 mm to convert from acres to hectares? That one will take me several minutes to solve by unit factoring. ;-)Things get real challenging when you move into factors which include area, volume, work/energy, pressure and MOIs ;-)BobFractions are for artists working in wood, stone or clay, not a man's dozer or a flying [email protected] us make it better!http://mtco.com/~rsam/fartslogo.jpg11/23/02
