The invention of the weighing scale is generally attributed to Daniel Gabriel Fahrenheit, who is better known for developing the Fahrenheit temperature scale. However, when it comes to the actual history of weighing scales, they have evolved over centuries. The first recorded use of a weighing scale dates back to ancient Egypt, around 2000 BCE. The Egyptians developed a form of balance scale for weighing goods, which later influenced the creation of modern scales.
In terms of the first documented invention of a mechanical weighing scale, Archimedes of Ancient Greece is often credited with developing principles related to balance and leverage. He is believed to have worked on the concept of the balance scale in the 3rd century BCE.
As technology advanced, the modern spring scale, a more precise way of measuring weight using springs, was developed much later in the 17th century by Robert Hooke, an English scientist.
So, while there isn’t one single “inventor” of the weighing scale, it’s a technology that developed over time, with contributions from various cultures and inventors.
