how come it can measure mass AND weight. i would understand if it could only measure one of the two, but both?

What in the world is Yugioh (sp?)
A triple beam balance works by putting known masses in one tray and your unknown sample in the other. The masses you name would be the same anywhere in the universe. Weight is peculiar to the planet you are on, but the masses used to balance the pan are the same.
Suppose it takes 1 kg to balance a sample of sugar you have. That 1 kg is a mass. To get the weight you would multiply by 9.81 to get a weight (which is a force) of 9.81 Newtons. The 9.81 is a constant that is true anywhere on the planet earth.
Mass and weight are not the same thing but they are related.

I have no idea in the world what it is other than a card game. I think it resembles dungeons and dragons, but I'm not sure. I would never ask something that would make fun of someone although I know it is common practice on this board sometimes, particularly in religion and spirituality.

The name pretty much tells it all -- Beam & Balance. A beam is balanced on a knife-edge. A sample to be weighed is placed in a pan on one end and a known mass is placed on the other end. The amount of the known mass is varied by adding or taking away small (known) amounts until the beam is balanced. At this point the mass of the sample can be determined from the required amount of known mass.
