The Definition of the Roman scale is presented as an instrument used for weighing, consisting of a lever with very uneven arms, with the faithful on the point of support. The body to be weighed is placed at the end of the smaller arm, and it is balanced with a pylon or constant weight that tends to run over the larger arm, where the scale is delayed.
Operation of the Roman Scale
In the case of the mechanical roman scales, these scales can be by counterweight or with elastic spring. The scales with counterweight act by means of a mechanism of levers that help to weigh.
This lever mechanism transforms the force corresponding to the weight of the object to be measured into a moment of force, which is balanced by means of the displacement of a pylon along a graduated bar, where the weight of the mass can be read.
The operating principle of these scales is similar to that of a balance, by means of mass comparison, through indirect measurement by weighing objects.

Roman Scale Inventor Brand
This type of primitive measuring instrument from the beginning consisted of a column with a shaft tied with a string at whose ends, in turn, were held by other ropes.
As the years passed, the Egyptians gradually modified their invention, so that by 1500 they added a plumb bob that allowed them to verify whether or not the instrument itself was leveled according to the requirements they themselves established.
The Romans were also able to create their own system for measuring weight, while the Egyptians were enriched by their own invention because they perfected it over and over again.
In fact, to the plumb bob they later added a needle, popularly known today as a felix, which indicates the balance between the plates of the measuring operator, who also points out the exact moment for the calculation of the weight.
But the Roman civilization, as mentioned above, did not remain stagnant in its invention. Around the year 200 B.C. they managed to make room for what later became known as the Roman hook.
The history of the scale and balance grew and this instrument was widely spread during the empire. It was in 1830 when Thaddeus Fairbanks invented what we know today as the Roman scale
Until our dates the scales have evolved to what we know today, but it has not stopped being the old and primitive means to provide reliability when making a measurement.
How to Make a Roman Scale ?
To make a Roman scale at home you will need the following materials
- Plastic from a chocolate egg.
- Jewelry chains that you can find at home, the thinner the better.
- A toothpick.
- Plasticine or any kind of dough that stays hard.
Now we move on to make the scale, from the plastic of the chocolate egg we cut the bottom part that will form the base of the scale, when cut it will be in the form of a plate.
- On the toothpick they make faces that will represent the weight measurements.
- Cut three pieces of the thinnest chain you can find, the measures in this case will be 3.5 cm.
- With wire we make three pieces in the shape of «ese» that will join the plastic with the chain which will perforate the plastic and will want to be located in the shape of a triangle.
- Use another similar wire to join the chains to each other and hold them with the toothpick
- Then we make and mount the upper hook of the scale.
To make the weight we cut a piece of wire and give the shape of the hook on one side and put a piece of dough with the shape of the weight on the other side. We paint them if desired and then mount the weight in its place. Once it is completely assembled, it is hung somewhere and that is it.
