An industrial weighing scale is a device that measures the weight or mass of objects in various industries. It can range from small bench scales to large weighbridges, and it can have different features and capacities. Industrial weighing scales are used for quality control, inventory management, and trade purposes.
This unit is similar in concept to the attoparsec, combining very large and small scales. When a barn (a very small unit of area used for measuring the cross sectional area of atomic nuclei) is multiplied by a megaparsec (a very large unit of length used for measuring the distances between galaxies), the result is a human-scaled unit of volume ...
The Schmidt sting pain index and Starr sting pain index are pain scales rating the relative pain caused by different hymenoptera stings. Schmidt has refined his pain index (with a 1–4 scale) with extensive anecdotal experience, culminating in a paper published in 1990 which classifies the stings of 78 species and 41 genera of Hymenoptera.
An article by Snopes in 2013 said the experiment was flawed because the methods used were suspect, the sample size was much too small, and the capability to measure weight changes too imprecise, concluding: "credence should not be given to the idea his experiments proved something, let alone that they measured the weight of the soul as 21 grams."
A Roberval balance made by W & T Avery Ltd. in England Detail: the bottom horizontal beam is hidden under the protective cover A Roberval balance shown responding to two masses of equal weight. The Roberval balance is a weighing scale presented to the French Academy of Sciences by the French mathematician Gilles Personne de Roberval in 1669.
An overview of ranges of mass. To help compare different orders of magnitude, the following lists describe various mass levels between 10 −67 kg and 10 52 kg. The least massive thing listed here is a graviton, and the most massive thing is the observable universe.
