Notice that now-days many of the "standard" SI units are named for long-dead scientests
Volt, Ampere, Watt, Henry, Farad, Joule, Hertz, Newton, Pascal, Celsus, Kelvin, Likely a lot more I can't remember. If you know a little history you can remember them. I think that is why they use proper names, because each has a back-story making it easier to remember. If you know some history of science the unit names are impossible to forget. They even changed the names of some old units to make them proper names. We used to say "Cycles" but now use "Hertz" and we used to use "Centigrade" but now "Celsius". So in this case, read a little about Blaise Pascal. He did many experiments with barometers so they named the unit of pressure (Newtons per square meter) after him. Likewise, it was Newton who un-scrambled the difference between force, weight, and mass so the unit of force is Newton. By now we all know what "0.8 MPa" means. It is 0.8 million newtons per square meter. > > > Operating pressure 0.15~0.8MPa supposed to tell me??? Need a translation > > from chinglish please. I haven't a clue what the heck 0.8MPa means. -- Chris Albertson Redondo Beach, California _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
