How much do I weigh? My scale one tell me

As a lab tech this is absolutely fascinating.
With the analytical balances in my lab, we calibrate with S1 weights daily. Both before the sample and at the end of samples. Usually if we get that much variation its due to air current. But then an analytical balance scale can be the tickiest piece of equipment in the lab. They seem to work best with the least variation in the acceptable range with a constant temperature of 70 degrees and no/low humidity.
My bathroom scale stopped having weird fluctuations when it was moved from the bathroom to the walk in closet. I have a theory that the "bathroom" scales may dislike constant moisture as much as the analytical scale in my work lab.
I'd take the number that came up most or average it all together. You could get really creative and do a geometric mean on them all. You have enough numbers a geo would be fun, but totally useless for weight.

@Danilynn1975 - that's why I was interested too! I'm an analytical chemist and weigh out milligrams or micrograms of compounds on a regular basis0

I test water for safety of discharge to the environment. Pretty fascinating stuff. I have tested bottled water against drinking water from the tap against EPA regulations and a lot of the pre-bottled water would be boil notices if it came from your tap.
Lab numbers and scales and seemingly useless data is often worth a great deal when other pieces of the puzzle become clear. Ambient Outside Temperature can have profound effects on so many things both chemically and biologically.0 -
Yeah scales do that. They're not 100% perfect. The differences aren't that high, so just take 1 measure and keep in mind it might be off by a pound or two before you start panicking why you haven't lost as much as you should since last time.0

^^^ you are so right, Danilynn1975!0

Possibilities:
- Cheap scale is cheap
- The batteries are getting low
- You stood on it slightly differently each time - where your center of gravity is on the scale might cause small differences?
- Poltergeist
I say take the weight that came up the most often and replace the batteries. Inexpensive bathroom scales are probably not the most finely-tuned expertly-calibrated machines, so I'm not really surprised when my scale can't make up its mind0 -

Is that all in one day?
That's natural weight fluctuation.
Weigh once a week, but remember there is always natural fluctuation. The important thing is to watch for the downward trend.0 -
Naw, it's the scale. It's all within minutes.
I too had a scale that did this, I got a new scale and it doesn't. I know because if I don't like the reading I get on and off it trying to get a different reading and it won't give me one.0 -
If that's a Fitbit scale, it's why I returned mine. A rep from the company said you have to step on it exactly the same way each time or it will weigh you differently. Also if you ever move the scale, at all, it needs to recalibrated. It just seemed like an expensive pain in the *kitten* to me so I took it back and got an "ordinary" scale.0

mine does that too. i've always put it down to when i step on my feet aren't in the exact same place. it has a complete hissy fit if i move it to a different part of the room!0
