HOW MUCH IS A NEWTON..

how much is a newton and does it have any thing to do with a gram

1 Newton is about 100 grams. The only time I've ever seen this unit of measure used was for measuring force, normally expressed in Newton meters per second, Newton meters per minute, or Newton meters per hour. It is the force required to lift one Newton (100 gm)to one meter, in the prescribed time unit. One Newton Meter per minute is equal to .74 Ft Lb per minute.

a newton is defined to be 1 kilogram-meter/second ^2

It is the most standard unit of force in physics.

Its is no where near "100 grams"
It is exactly ONE KILOGRAM. (1000 grams)

It is, more precisely, the force required to accelerate an object that has a mass of one kilogram to a speed of one meter per second.
Nothing more.

old scale that measure in newton that i have seen are just measuring kilograms. Sometimes torque devices use newtons but technically they meat kilogram-meters or foot pounds.

1 newton = 0.1019716 kilogram-force

what?
maybe there is something i don't know about here. Is the word "newton" used for another unit of measure?
The newton is the most basic force unit used by (well students really) physicists. Its named in honor of the "father of physics"
Its on like page ten of every physics book in the world.

1N = 1kg-m/s^2

(okay page 90 of the book i taught from)

Oldherper, having read many of your posts i have great respect for your knowledge but i have to tell you unless "newton" is for some reason used as a unit of measure and is NOT consistent with the kilogram, which would be ridiculous, (but that doesn't make it out of the question), or i am totally insane, then well something is wrong here. Except for being the place where part of Boston College campus is (and many other towns in the English-speaking world) and an outdated object-oriented computer language and the name of a cookie, i can't think of what else a Newton is besides its fundamental definition as the unit of foced based on the kilogram.
Crazy. I guess i'll have to look this one up.

there is the newton centimeter, a metric unit of torque equal to 0.01 newton meter but i mentioned this as the unit discussed on old torque scales.

and to think i was losing my mind....8 years wasted and to have learned nothing! : )

explaination of the realtive obscurity of kilogram force as a (formerly) valid accepted unit

Interesting as this unit appears to have little advantage.
