I'm wondering how temperature sensitive common spring loaded bathroom
I've got a feeling the reported weight changes by about 1 percent when
the temperature in the bathroom ours is in varies between "cool" and
"hot" by about 15 degrees F, reading lower when cool and higher when hot.
That would coordinate with the springs getting "softer" when warm,
Whay say guys?
No, not until the spring is heated enough to change the metal's structure.
This would be a one-time event, not repeatable and would occur at many
hundreds of degrees.
Springs will get slightly longer at high temperatures but 1% is a *lot*. This
would mostly be offset by adjusting the zero offset, anyway.
What does change from day to day and even hour to hour is our weight.
Remember, a 16oz glass of water weighs a pound. A couple of those, and you
have your 1% (my weight easily changes 2-3% over a day and probably that much
over a week, as well). This is why they tell us to weigh ourselves at the
same time every day - not because the scale has gained weight. ;-)
*will* make it inaccurate. I can get on and off my scale on a tile
floor a dozen times and it will read within 1/10th of a pound each
time. [out of 230 or so pounds]
If I move it so its feet are on 4 different tiles, it can vary as much
as a couple pounds.
Bathroom scales are not all that accurate to begin with. 1% is not
much change as you vary that much from morning to night anyway. Doubt
temperature would make that big of a difference, but you'd have to
check it with a constant weight, not your body.
