Being able to measure right down to molecular level has paved the way for many of the 20th century’s greatest discoveries including the research on space.
Who invented the first kitchen scale?
It is only starting in the late 18th century that new ways to measure mass appeared that didn’t rely on counter-weights. The spring scale was invented by Richard Salter, a British balance maker around 1770.

What is difference between weighing scale and balance?
Scales and balances are both weighing machines. However, the critical difference is that a scale measures weight while a balance measures mass. Weight is the force of gravity on an object measured using a scale. The basic unit of measurement for mass is the kilogram.
Who invented the scale during the Renaissance?
The weighing scale didn’t know any major technological improvements until the industrial era. It is only starting in the late 18th century that new ways to measure mass appeared that didn’t rely on counter-weights. The spring scale was invented by Richard Salter, a British balance maker around 1770.
