Before creating the 5 weights, The ancients had to create a 1 gram weight to measure out all their other weights.

So the ancients had a bunch of super fine sand which was made entirely of the same material, and every grain was its most basic material. They had 121 grams of this sand. They also had a tube which could hold exactly 121 grams of sand, no more, no less.

How do the ancients weigh out 1 gram of sand?

how did they know that they had 121g of sand in the first place?
