I have a cheap digital scale at home. But, to make sure it's accurate, I weight my 5 lb weight on it before I weigh myself. It always says 5.0 when I weigh my weight. So ..... I'd assume it's accurate.
I weighed myself around 4:00 today at home, then I had a doctor appointment around 5:00.
Naturally, they weighed me. (They have a digital scale too). I was 4lbs heavier!!! What the???
Which one would you trust?
The doctor's scale is probably more expensive and higher quality.
See, that's what I would think, but that's why I mentioned I weigh my 5 lb weight on my scale. And it accurately weighs that.
I don't really think that bathroom scales are made to measure such small weights.
It doesn't really matter though--what matters is your weight trend. As long as you're consistently using the same scale, I wouldn't worry about it.
weights are going to vary from scale to scale. Also did you eat or drink anything prior to your doctors appointment? I wouldn't worry about it, hell don't even rely on scales you have to go by how you look and feel not a number.
Just because the doctor's scale is fancier, doesn't necessarily guarantee accuracy. Sometimes scales, especially those that are used a lot, need to be re-calibrated.
And autopilotfrank is right, there is so much that can vary about how you weigh. For instance, if I weigh myself first thing in the morning, I always weigh less than when I weigh myself in the afternoon (same scale) by anywhere between 1-5 lbs.
If your weight is going in the direction you want it to, that's what really matters!
I agree with Adrienne in #3.
Your profile says you weigh 107 lbs. 107 lbs or 111 lbs, you're thin at both weights.
It's just something that you want to know though! lol
If you really really want to know then weigh yourself before going to the doctor. Don't eat or drink any thing and note the time lapse between the two weighing. Then calculate how much weight a person with your weight would lose through metabolic respiration for that time period. Then you can calculate the real difference. Chances are the variation on your scale and the doctor scale will muddle your numbers anyway. You can always try to get more precise but don't necessarily get more accurate.
I weigh at home first thing in the morning butt naked. When I go to the doctors office I've usually eaten some food prior and drank water/coffee. I also weigh there fully clothed. 4 lbs is nothing. Your digital is probably just as accurate as the doctors office.
