Weight (SI Unit) = Kg or N?
Mass (SI Unit) = Kg or N????
I don't know if Newton is the SI unit for mass or weight...I'm totally confused...

Newton is the SI Unit for force which in the US and Britain is usually measured in foot pounds.
Blame the French for your confusion.
According to Wikipedia: http://en.wikipedia.org/wiki/Cow_milk
"The International System of Units (abbreviated SI from the French Le Système international d'unités) is the modern form of the metric system. It is the world's most widely used system of units, both in everyday commerce and in science.
The older metric system included several groups of units. The SI was developed in 1960 from the old metre-kilogram-second (mks) system, rather than the centimetre-gram-second (cgs) system, which, in turn, had a few variants."
According to Wikipedia: http://en.wikipedia.org/wiki/Newton
"A newton is the amount of force required to accelerate a body with a mass of one kilogram at a rate of one meter per second squared. Algebraically, N = kg·m/s²."
Mass is a property of matter that is measured by its weight.
The weight of something changes with the gravity field, but the mass remains constant.
On earth under 1G an item that weighs 60 lbs will have a mass of 60 lbs. On the moon though it has 1/6th the weight so it has a weight of 10 lbs, but the mass hasn't changed.

Newton is the SI unit for weight
Kg is the SI unit for mass

SI Unit of weight/force = N (newton)
SI Unit of mass = kg (kilograms, notice the lower-case k)

the si unit for weight is N. The SI unit for mass is Kg.

Newton: unit of force; SI symbol = N.(Note: Upper case N, not n.) Second: unit of time; SI symbol = s. (Note: lower case s, not S; S is used for something else.) Metre: unit of length; SI symbol = m. (Note: in the SI naming scheme, which is based on the English Language, it's 'metre', not 'meter'. A 'meter' is a device for measuring something!) Kilogram: unit of mass; SI symbol = kg. (Note: lower case k, not K) ■

weight: newtons (N)
mass: kilogram (kg)
Think of it this way, newtons are the SI units for force. Weight is the force of gravity pulling your mass down. (W=mass*gravity)

mass is m and its SI unit is the kilogram.
forceis F and its SI unit is the newton. Density is row and its SI unit is mass/volume.
