Does it have to do with accuracy?

One issue is that gravity varies by up to 0.7% depending where you are on earth and that’s way too big of an error to ignore for things like boxing weights, where ounces matter over hundreds of pounds.
Balance scales are unaffected by changes in gravity because they’re comparing mass to mass and gravity affects both sides equally. Electronic scales are measuring force, not mass, so they need to be accurately calibrated in each location.

For something like boxing where both competitors use the same scale, it’s a lot easier to prevent cheating with a mechanical version. Firmware can be silently and invisibly changed (and automatically revert its self after the weigh-in). Changing the readout on a mechanical scale would leave evidence.

Hospitals can work without any digital devices. They did it before, they can do it now, and that will help them. For sporting events it’s probably to give dramatic effect when determining whether you qualified for your weight class.

While yes, a digital scale can tell you a person’s weight to the thousandths place with pinpoint accuracy, there’s this old saying, if it ain’t broke don’t fix it.
Turns out that a person’s weight fluctuates so much during the day from many factors (whether you just pissed, or ate a huge meal, or ran a mile and breathed and sweated a lot, or haven’t passed in hours). So the level of accuracy provided by a digital scale isn’t really needed. They are also a lot harder to fix and need to either be constantly plugged it or require batteries, which a mechanical scale doesn’t. And a mechanical anything is less prone to damage than the same thing but digital

My dr office and hospital have digital scales. I was in the hospital last night with my daughter and they weighed her on a digital scale and weighed her in kilograms. It was in the US so they warned us that it was kilos.
