| It's so simple, that I don't know why I didn't think of this before; but the _standard_ force, and weight is ONE/g: That is each system of weights and measures has a different standard of force, and/or weight depending of their numerical measure of the acceleration (g) of free fall. The dyne is 1/981 cm/sec/sec; the newton is 1/9.81 m/sec/sec, and the pound is 1/32.174 feet/sec/sec: So that for any _unit_ of mass, w/g = 981 dynes/981 cm/sec/sec = 9.81 N/9.81 m/sec/sec = 32.174 pounds/32.174 feet/sec/sec = (the constant) ONE; which is equal to the net force (f) exerted on, and/or by that _unit_ of mass, divided by the acceleration (a) that it causes. Any body's "gravitational mass" (w/g) is equal to its "inertial mass" (f/a). Don |

| Jeremy Watts wrote: before; of weight free it? fundamental The idea of standardizing force and weight Is only complicated in your great mind Jeremy. On this old world that we call Earth, because that's the part we live on; there are really only two viably consistent systems of weights and measures: The customary pound-foot system, with its derived, invariant slug as its _unit_ of mass, and the SI newton-meter system, with its derived, invariant kilogram as its _unit_ of mass. When we do start to actually live on other worlds; then we may want to develope a Systems Interglobal. For now we only need to have the standard forces and weights that I have listed: the = pounds/32.174 (f) acceleration mass" Notice that any body's "gravitational mass" (w/g) is equal to its "inertial mass" (f/a): They are invariable constants, anywhere; anytime.

You must be the guy responsible for not knowing how to look forward and not code the dates properly in all the programs that never took into account that using only the last two digits of the year might not be good when 2000 rolled around. So hey, why don't you just create a crippled system this time too. don to engineers: "What? Come up with sensors that measure speeds greater than the speed of sound? We'll never need to worry about that since the speed of sound will never be broken." |
