Why are bathroom scales adjustable?

After a while, bathroom scales lose their calibration. By making them adjustable, one can make sure that what it thinks is zero actually is. Scientific scales are adjustable for that reason and another: one can put a container on it, tare it (or set it to zero), and then weigh a material. This way, the weight of the container is easily ignored.

Maybe turning it back gives you the ability to weigh something that exceeds the weight indicated on the dial.
-
Because the truth hurts!

Air pressure varies at different elevations, and many scales have to be recalibrated on a regular basis. My electronic one calibrates when you put a foot on it. You then take your foot off, and step on when it tells you that it is ready.
-
Because some people are just that insecure.
-
2 reasons: first, because none of them work! secondly, because many people like "their" (own false/lower) weight better than the true weight.
-
So that really fat people can magically make themselves skinnier and feel better about themselves.
-
So when someone weighs themselves and finds out their 20 stonne you can change back before they starve themselves.
-
Officially, so that we can correct them when they start to become decalibrated, as eitheeli says. Unofficially, so that we can imagine we wear slightly less/ a lot more/ nothing at all! (I can recommend doing this, it is a very surreal experience being weightless)
-
So that we can continue to kid ourselves that all the chocolate we eat is having no affect on our weight at all.
-
To make us all feel better about ourselves.....
-
so overweight people can lie to themselves.
-
beacuse they are sooo inaccurate
-
So our wives can dial in their desired weight. Sheesh, people! Think! :)
-
So one can cheat.
-
To make us feel better. ;-)
