I bought a new bathroom scale and it gave me an inaccurate reading. Why is it doing that?

Options
I bought a new bathroom scale. I'm 14stones and 5lbs. I know that I haven't gained weight because I work out a lot and I eat well and lost weight recently. This morning when I weighed myself on the new scale it showed as 15stones. That can't be right, because I have another scale and it always gives me accurate readings. What is going on?

    Have you tested it with a weight? I would make sure before taking another step.

    Test your scales by placing a known weight on them to see if it gives an accurate reading.

    If you already had an accurate scale why did you buy a new one?

    Put something with a weight you know, like a 4 lb bag of flour or a dumbbell, on the scale to check its accuracy.

    I agree with this... even if the new scale is a bit "off", you can usually calibrate it downward to accurately weight the known object. Then, theoretically, it should weigh you accurately.

    If it's reading is different from what you expect, it will still be able to tell the difference when you drop a whole pound, ...5 pounds, or how ever many pounds. A smart Dr. told me to just pick a scale and stick with that scale. Your scale knows what a pound is and it will tell you when you lose a pound.

    Have you ever thought that your 1st scale might be off?

    That was my first thought too!

    Most of us dont weigh exactly the same every day and weight definitely fluctuates throughout the day. Lots of possibilities for variations.

    Different scales commonly give different readings. Choose one scale to use to measure your progress with.
    I personally would put a weight on the scales and see which one is closest to correct.

    Every scale needs to be calibrated, especially after it is moved. And then regularly, every few months.

    Maybe your old scale is wrong. Scales lose their validity over time due to just normal use.

    I did the same thing- my new scale weighs me heavier than my old one. I had bought a new one instead of just buying a battery- now my old scale says i gained weight also- yuck!

    I see that they can both be wrong honestly.. this why you use one and only one. If the old one absolutely has your correct weight, why buy a new one?

    Now if you put a known weight on the scale and it is off there is an issue. If it came with batteries, replace those.

    OP hasn't come back. Has she discovered the new scale was probably the more accurate one and ragequit? Taken a sledge hammer to the new lying scale?

    All scales are inaccurate. Unless they have been calibrated in situ by someone with the proper equipment, and then recalibrated on a regular basis, they are just an estimate. The point of them is to track a change in weight, and they will do that just fine if you pick one and stick with it, as others have said. And I'm afraid the new one is likely to be more accurate, as it was calibrated more recently.

    I would look at the surface it's on! If it's on hardwood floor, an uneven tile, etc. it's pretty common to get funky readings!
