    I am making a balance but I do not have any objects whose weight I know. I was wondering if anyone had a list of common objects that weigh roughly 1g, 5g, 10g, 50g, 100g, etc.

    You need to think in ''Newtons'' which is a vector force quantity. One Newton is roughly the same as the gravitational mass of a cooking apple. It is defined as that force necessary to provide a mass of one kilogram with an acceleration of one meter per second per second.


    Only the mind can think twice simultaneously about a subject, but only one thing can inexorably come out of it. A choice.

    Look up the standard weights of coins in your country.

    Good, clean, new coins are probably the way to go. They have to be made to some pretty exacting standards. (I'm not sure if old, corroded coins would still weight the same though.)

    Also, a balance measures mass, not weight. A 1 kg object will balance with any other 1 kg object no matter what gravity/acceleration the system is under.

    Edit: Oh yeah. Another good standard to use would be water. Purified water has a consistent, easy-to-use density, so if you can measure out the volume accurately, you can know its mass accurately.
