    Weight is made by a force which is gravity.

    But mass does. Mass and weight are not the same thing. Weight is the measure of the effect of gravity on mass. It is not mass, but is a product of mass and gravity.

    Mass isn't weight, so your sentence is meaningless.

    And yet you can't provide a link to this "definition" while simultaneously ignoring the definitions that we've linked to.

    No it's not.

    Correct.

    Since the maths uses MASS and not weight you're wrong.

    Not possible, since you haven't specified a density.

    Only on Earth.
    Not any where else (unless that place also has a 1G gravity).

    Read the definition ,

    give the mass of any object and the answer is a weight, weight is equal to the force of gravity, which is the force of attract centripetal .

    I know weight is not really a thing, that is what I just said, come on I am waiting give the mass for a 2cm3 cube, you know the answer is a weight and I am correct, so why continue trying to lie, when I proven it already?

    because you know it shows you lie! and that is why you will not answer.

    My question was, what units is weight measured in. Do you not know the answer to this year 7 school question?

    Newtons is the term for weight and kilogram is the term for mass. In everyday terms however we use kilogram for weight just because that has been the common usage. Perhaps this is what is causing your confusion?

    It's like referring to how bright a light bulb is in watts. Everyone "knows" how bright a 100 watt light bulb is but actually "watt" tells us nothing about how bright the light is. It's a measure of how much power it consumes.

    We should be using lumens for output. It became comon usage (watts) only because light bulb technology didn't change for so long that it was assumed that the bulb being referred to was incandescent and everyone knew from past experience about how bright that bulb was but watts has nothing to do with brightness.

    It's similar to the way kilogram is misused for weight in common usage.

    different units

    Is that why you haven't provided the link I've asked for?
    Because you know you're lying.

    And you're wrong.
    Unless you specify the density of the object then I can't tell you the mass. (Nor the weight).
    Regardless, mass and weight are NOT the same thing.

    0.981n is = 100g it is the same thing painted a different colour

    What's the mass on the Moon? 100 g.
    What's the weight on the Moon? Considerably less.
    Therefore they're NOT the same thing.

    strange how 0.981n =100g and 100g = 0.981n if that is not the same then wow.

    What is the SI unit of weight,(i.e. the unit that goes with kg, metres, Joules, etc) ?

    If you cannot answer this, then it will give us all a useful indicator of the level of your scientific literacy.

    100g is the mass weight, you lie.

    If I set up a paypal account, will anyone give me long odds that TC will never understand or admit to what he's being told?

    No, he's right and again any alert 11yr old schoolkid knows this.
