Does it have to do with accuracy?
In: 117
I’ve worked in sports for about 15 years now. The analog scales are more accurate, more reliable, last longer, and are very easy to calibrate. A solid detecto scale will cost about 100$ and last for 30 years with no issues. Also, side note, having worked on Navy ships they also work surprisingly accurately while underway.
I’m 40 and have never seen mechanical scales in a doctors office or a hospital, interesting! Only ever seen those sliding scale ones on American TV shows or movies.

I believe mechanical beam scales are technically balances and not “scales” with like springs or anything that require calibration.
You can’t refute the measure of a beam scale, and you can validate the weight of the…weights with a known good reference set.
I remember my chemistry teacher going on about why it was important but not what was said that day.

Balance scales actually measure mass.
The balance scale would read the same on the moon or on another planet where gravity was stronger or weaker.

Fun fact: digital scales weigh weight and those mechanical slide scales actually measure mass. What’s the difference? A mechanical scale would still be accurate on the moon while a digital would real about 1/3rd. Mass is intrinsic to the object. Weight is a measure of the force of gravity between 2 objects. On earth we see them as interchangeable because the force of gravity is nearly constant.
